Electrochemical Removal of PFAS by Boron-doped Diamond Electrode ZHANG Senchong, LYU Jitao, WANG Sen, LYU Jilei, WANG Shaolong, WANG Yawei Chem. J. Chinese Universities    2025, 46 (8): 20250096-.   DOI: 10.7503/cjcu20250096 Abstract （1074）   HTML （9）    PDF（pc） （5983KB）（168）       Knowledge map    Save In this study， six boron-doped diamond（Nb/BDD） electrodes with different boron doping levels were prepared using niobium flakes as the substrate by microwave plasma chemical vapor deposition， and the effects of different boron doping levels on the electrochemical performance of Nb/BDD electrodes and their oxidation of perfluorooctanoic acid（PFOA） were investigated and applied to the electrochemical removal of different perfluorosulfonic acids（PFASs）. The results showed that with the increase of boron doping level， the grain size of the Nb/BDD film gradually decreased and the electron transfer rate on the electrode surface gradually increased， but the decrease of film quality leads to the increase of its exfoliation rate. Na2SO4 was used as the electrolyte， and the Nb/BDD electrode as the anode was able to oxidize PFOA within 120 min at a current density of 30 mA/cm2. PFOA degradation rate to 78.3% and mineralization rate to 78.1% within 240 min. Among the six Nb/BDD electrodes prepared with different boron doping levels， the medium and low-doped Nb/BDD electrodes have higher degradation and mineralization ability for PFOA， indicating that the efficient electrochemical removal of PFAS can be achieved by regulating the boron doping level of BDD. The analysis of the degradation products indicated that the electrochemical degradation of PFOA follows the law of carbon chain step-by-step removal， in which the direct electron transfer between the anode and the pollutant is the key initiation step of degradation. The electrochemical degradation of PFSA and perfluorocarboxylic acid（PFCA） with different chain lengths reveals that the length of the carbon chain is positively proportional with the degradation rate and mineralization rate of PFAS， and thus the short-chain products generated by the degradation are the main reason for limiting the complete mineralization of PFAS. In the future， more attention needs to be paid to the efficient removal of short-chain and ultrashort-chain PFAS in order to meet the demand for the complete detoxification of PFAS through electrochemical technologies.

Robust， Self-healing Polyurethane Hydrogel Enabled by Dual Crosslinking of Dynamic Disulfide and Hydrogen Bonds YANG Bing, DING Xia, XU Jun, LI Ye, GU Rui, ZHANG Hui, HOU Zhaosheng Chem. J. Chinese Universities    2025, 46 (9): 20250098-.   DOI: 10.7503/cjcu20250098 Abstract （883）   HTML （8）    PDF（pc） （8252KB）（204）       Knowledge map    Save This study developed a new kind of self-healing polyurethane hydrogels（SPUGs） through a synergistic crosslinking strategy combining dynamic covalent disulfide bonds and non-covalent hydrogen bonds. A specifically synthesized quadrifunctional crosslinker， 3，3'-disulfanediylbis（propane-1，2-diol）， was employed to react with poly（ethylene glycol）-based polyurethane prepolymers， followed by solvent-exchange method to produce SPUGs. The physicochemical properties of SPUGs and lyophilized gels（DSPUGs） were characterized comprehensively， and the results revealed that the dual-crosslinked systems exhibited enhanced thermal stability［temperature at 5% mass loss（T5%）>250 ℃］ and low glass transition temperature（Tg<0 ℃）. With the increase of disulfide bond content， the surface hydrophilicity and equilibrium swelling ratio of SPUGs reduced， while water-retaining capacity increased. Mechanical tests demonstrated that SPUGs exhibited elastic deformation and possessed outstanding tensile properties， compressive toughness and fatigue-resistant capacities. SPUG-II with a moderate crosslinking density achieved a maximum tensile strength of 112.2 kPa， elongation at break of 459.4% and fracture toughness of 267.6 kJ/m3. The double dynamic bonds endowed SPUGs with high self-healing efficiency（≥90% at 50 ℃ for 2 h） and redox-triggered reversible gel-sol transitions. Methyl thiazolyl tetrazolium（MTT） assays confirmed favorable cytocompatibility with cell survival rate exceeding 80% after 72 h incubation. The SPUG hydrogels with superior mechanical properties， reversible gel-sol transitions， high self-healing capability， and good biocompatibility indicated promising prospects in biomedical applications.

Aggregation Induced Emission Enhancement of Ligand-Engineered Au Nanoclusters YE Weiqing, LU Hui, CHEN Wanjing, LI Ningjing, ZHANG Yu, WANG Lihua, LI Jiang, ZHU Ying, LI Mingqiang, FAN Chunhai, JIA Sisi, CHEN Jing Chem. J. Chinese Universities    2025, 46 (8): 20250100-.   DOI: 10.7503/cjcu20250100 Abstract （796）   HTML （28）    PDF（pc） （5882KB）（252）       Knowledge map    Save The aggregation-induced emission（AIE） properties of gold nanoclusters（Au NCs） exhibit significant potential for applications in bioimaging， chemical sensing， and optoelectronic devices. However， developing effective design strategies to achieve strong aggregation-induced emission enhancement（AIEE） in Au NCs remains a challenge. In this paper， we report a ligand engineering approach to achieve remarkable AIE enhancement in Au8 nanoclusters. The quantum yield of aggregated Au8 NCs showed a ca. 90-fold increase compared to their solution state， with corresponding emission intensity enhancement reaching ca. 560-fold. Through combined optical characterization and metastable component tracking in aggregated systems， we elucidate the underlying AIEE mechanism. Both AIEE and crystallization-induced emission enhancement（CIEE） were activated through ligand engineering， which facilitated （1） shortened inter-cluster distances（from 1.31 nm to 0.72 nm） and （2） effective suppression of intermolecular rotational/vibrational relaxation. This steric-hindrance-reduction strategy establishes a new paradigm for precise modulation of photoluminescence in gold nanoclusters across both aggregated and crystalline states.

Extending the Polarizable Bond-dipole Model to Enable the Rapid Prediction of the Conformational Stability of Cyclic Peptides ZHENG Xiaohan, ZHU Jiayi, LI Xiaolei, HAO Qiang, WANG Changsheng Chem. J. Chinese Universities    2025, 46 (10): 20250173-.   DOI: 10.7503/cjcu20250173 Abstract （749）   HTML （7）    PDF（pc） （2901KB）（72）       Knowledge map    Save Cyclic peptides possess unique conformational stability， diverse biological activities， and favorable target specificity， making them important lead compounds in drug development. Rapid and accurate prediction of their conformational stability not only aids in uncovering the molecular mechanisms of protein misfolding， but also provides a theoretical basis for target identification and intervention. This is of great significance for the rational design of structurally stable and highly active cyclic peptide-based drugs. In this paper， the polar chemical bonds C=O， N—H， C α —H and C—O， O—H in cyclic peptides are regarded as bond dipoles. The permanent dipole- permanent dipole interaction is used to describe the electrostatic interaction in the system， and the permanent dipole-induce dipole interaction and induce dipole-induced dipole interaction are used to describe the polarization. The bonded terms， including the bond-stretching， angle-bending， and dihedral torsion， are also introduced. The polarizable dipole-dipole interaction model is thus developed into a potential function that can be used to rapidly calculate the relative energies of different conformations of cyclic peptides. The potential function is applied to 9 cyclic peptides， total 33 different conformations to rapidly predict the conformational energies of these conformations. The conformational energies of these conformations are also calculated using the AMOEBA and DLPNO-MP2/aug-cc-pVTZ methods. The calculation results show that， compared with the DLPNO-MP2/aug- cc-pVTZ conformational energies， the linear correlation coefficient R2 of our model is 0.9784， and the root mean square deviation is 13.43 kJ/mol， slightly better than the linear correlation coefficient 0.9682 and root mean square deviation 16.28 kJ/mol of the AMOEBA method. The results of structural optimization and frequency calculation further suggest the rationality of our model. Furthermore， compared with the AMOEBA polarizable force field， our polarizable model significantly reduces the number of electrostatic terms. The model proposed in this paper may provide a new tool for the research and development of novel cyclic peptides as drug candidate molecules.

Effects of Surface Modification Strategies of Spherical Silica Particles on Properties of Epoxy Resin Composites for Electronic Packaging ZHANG Lili, HU Haijun, LI Houwen, NIE Xingcheng, LI Bin, ZHANG Hailin, HU Qiaoju, ZHENG Dezhou, ZHANG Gouqing, JING Jinfeng, LIU Wenxing, GAO Changyou Chem. J. Chinese Universities    2025, 46 (10): 20250145-.   DOI: 10.7503/cjcu20250145 Abstract （742）   HTML （10）    PDF（pc） （6810KB）（484）       Knowledge map    Save The effect of silane coupling agent（SCA） interfacial modification on the properties of silica particles/ epoxy composites was systematically investigated to address the performance bottlenecks of epoxy resin-based electronic packaging materials in terms of high thermal conductivity， low dielectric loss， and moisture and thermal stability. The successful grafting of silane coupling agents onto the silica particle surface was verified by surface energy spectroscopy analysis， and epoxy resin-based packaging films with high filler content（50%， mass fraction） were prepared to compare the overall performance of the composites before and after modification. The incorporation of γ-glycidyloxypropyltrimethoxysilane（KH-560） enhanced the interfacial bonding strength of resin through the participation of epoxy groups in the cross-linking reaction. The resultant composites exhibited an optimal glass transition temperature of 170.38 ℃， a thermal conductivity of 0.15 W/mK， and a tensile strength of 102.79 MPa. The resin prepared by using N-phenyl-3-aminopropyltrimethoxysilane（KBM-573）-modified silica particles exhibited a water contact angle of 114.9° and slightly lower mechanical properties due to the hydrophobicity of the benzene ring and conjugation effect. The γ-aminopropyltrimethoxysilane（KH-540）-modified system demonstrated limited improvement in dielectric properties and hydrophobicity due to the amine polarity. The present study elucidated the synergistic effect of modified silica particles on the mechanical， thermal， and electrical properties. This finding provides a theoretical basis for the targeted optimization of electronic packaging materials. Table and Figures | Reference | Related Articles | Metrics

Synthesis and Near-infrared Reflective Properties of Rare-earth-doped Bi2－x Gd x MoO6 YAN Junlin, LI Xiaodong, LIU Dongyang, LI Mingzhe, ZHANG Su Chem. J. Chinese Universities    2025, 46 (9): 20250088-.   DOI: 10.7503/cjcu20250088 Abstract （712）   HTML （12）    PDF（pc） （7683KB）（1329）       Knowledge map    Save In response to the escalating challenges of global climate change and urban heat island effects， the development of energy-efficient functional materials with high near-infrared（NIR） reflectance and effective thermal regulation capabilities has become a research focus. Traditional oxide materials， such as Bi2MoO6， still exhibit certain limitations in NIR reflectance. In recent years， rare-earth-modified molybdate materials have attracted significant attention in the field of NIR-reflective coatings due to their excellent optical response characteristics and structural stability. In this study， Gd3+-doped Bi2－x Gd x MoO6（x=0， 0.2， 0.4， 0.6， 0.8， 1.0） NIR reflective materials were synthesized via a solid-state reaction method. The obtained samples were systematically characterized by X-ray diffraction（XRD）， scanning electron microscopy（SEM）， energy-dispersive spectroscopy（EDS）， Fourier transform infrared spectroscopy（FTIR）， Raman spectroscopy， near-infrared（NIR） reflectance spectroscopy， thermogravimetric-differential scanning calorimetry（TG-DSC） and thermal insulation performance tests. The results indicated that the synthesized samples exhibited good crystallinity. Gd3+ doping induced a bandgap narrowing （from 2.87 eV to 2.80 eV）， leading to a redshift of the absorption edge and enhanced absorption in the 450—600 nm blue-green region， resulting in a more pronounced yellow hue and enabling effective color modulation. All Bi2－x Gd x MoO6 samples exhibited high NIR reflectance， with values exceeding 87.68%， significantly higher than that of TiO2（75.66%）. In particular， the sample with x=0.4 demonstrated the highest NIR reflectance of 90.11% and a NIR solar reflectance of 89.53%， which are 14.45% and 9.24% higher than those of TiO2， respectively. Infrared lamp irradiation experiments further confirmed the superior energy-saving and thermal insulation performance of the materials. TG-DSC analysis revealed that Bi2－x Gd x MoO6 pigments possess excellent thermal stability， allowing for long-term application in high-temperature environments. These findings offer a new and promising alternative for high-performance thermal insulation materials. Table and Figures | Reference | Related Articles | Metrics

A Novel Anthracene-based Two-dimensional Covalent Organic Framework Nanosheet for Rapid Singlet Oxygen Capture and Controllable Release AN Jing, MIAO Bo, ZHAO Tongyi, SONG Jialong, ZHANG Wenyu, YUAN Bizhen, LIU Yaozu, ZHONG Tian, FANG Qianrong Chem. J. Chinese Universities    2025, 46 (12): 20250117-.   DOI: 10.7503/cjcu20250117 Abstract （657）   HTML （81）    PDF（pc） （4477KB）（315）       Knowledge map    Save Singlet oxygen（¹O₂） is a highly reactive species with strong oxidizing properties， making it valuable in various applications， including photodynamic therapy， organic synthesis and material science. However， its short lifetime and high reactivity present significant challenges in its practical use. To overcome these challenges， the development of efficient materials for ¹O₂ capture and controlled release has attracted considerable attention. Covalent organic frameworks（COFs）， with their unique crystalline structure， high porosity and exceptional stability， have emerged as ideal candidates for ¹O₂ storage and transfer. In this study， we designed and synthesized a two-dimensional anthracene-based COF（2D An COF）， which was further exfoliated into nanosheet（2D An COF-nanosheet） to enhance its performance. Fluorescence spectroscopy analysis demonstrated that the 2D An COF-nanosheet exhibited a significantly higher ¹O₂ capture rate compared to the bulk COF， which can be attributed to their more exposed active sites. Both the 2D An COF and its exfoliated nanosheet showed excellent reversibility in ¹O₂ release when exposed to external thermal or light stimuli， with no significant degradation in performance after multiple cycles. The results highlight the potential of 2D COF materials， particularly in nanosheet form， as efficient and stable platforms for ¹O₂ storage and release. This work provides new theoretical insights into the design of ¹O₂-responsive materials and opens new avenues for applications in photodynamic therapy， photocatalysis and other fields requiring precise control over reactive oxygen species.

J. Chinese Universities    2025, 46 (9): 20250068-.   DOI: 10.7503/cjcu20250068 Abstract （625）   HTML （14）    PDF（pc） （20562KB）（136）       Knowledge map    Save Combination of chemotherapy and photothermal therapy can cover the entire tumor area， achieving an effective synergistic treatment performance. In this study， covalent organic frameworks（COFs） with unique pore structure and excellent chemical stability were utilized as the shell， and Fe3O4 nanoparticles with favorable photothermal properties were adopted as the core to construction a core-shell structured drug carrier with a particle size of approximately 200 nm. The antitumor drug doxorubicin hydrochloride（DOX） was encapsulated into the pores of COFs. Subsequently， the composite material was modified with the thermosensitive material， poly（N- isopropylacrylamide）（PNIPAM）， which was used to seal the surface of the composite. Furthermore， under irradiation with 808 nm laser， Fe3O4 nanoparticles rapidly converted light energy into heat energy， thereby generating a temperature change that achieve two purposes， on the one hand， the temperature change reached the lower critical solution temperature of PNIPAM for phase transition， causing the structure contracts inward and thus achieving the controlled release of drug molecules. On the other hand， the high temperature could kill cancer cells effectively， thus exhibited chemo-photothermal tumor therapy performance. Finally， carbon dots were grafted on the surface of the system to achieve the folic acid-mediated target controlled release mechanism， and a temperature-sensitive drug controlled release system was constructed successfully. The system exhibited highly antitumor performance by combining with chemotherapy and photothermal therapy. Table and Figures | Reference | Related Articles | Metrics

This study developed a continuous-flow microchannel technology for the critical synthesis steps. By optimizing the cyclization and hydrolysis processes， the reaction time was reduced from 90 min to 4.8 min， achieving a 65.2% yield and 95.2% purity. The novel process significantly improves reaction efficiency and product quality， offering a promising approach for the industrial production of clethodim.

This work focuses on the development of a visible-light photocatalytic three-component difunctionalization of alkenes using silylborates and acyl ammonium salts to access ketone derivatives. Control experiments and DFT calculations revealed that reaction proceeds via a single-electron transfer cascade process between a base/silylboronate complex and an acyl ammonium salt， triggered by a photocatalyst， generating silyl radicals and acyl radical anions. Subsequent sequential coupling with alkenes affords β-silyl ketones. This method features excellent functional group tolerance， mild reaction conditions， and broad substrate scope.

In⁃situ Construction of Co-MOFs/Carbon Fiber Composite Cathodes and their Efficient Degradation of Tetracycline in the Electro-Fenton System QIN Caiyi, LI Juan, LI Ying, ZHANG Jiuwen, LONG Hanyi, LI Xinyu, MI Nan, LIU Jinwei, LI Hua Chem. J. Chinese Universities    2025, 46 (8): 20250118-.   DOI: 10.7503/cjcu20250118 Abstract （583）   HTML （7）    PDF（pc） （5706KB）（103）       Knowledge map    Save The traditional Fenton method catalyzes the H₂O₂ by Fe²⁺ to generate hydroxyl radicals （•OH）， which can efficiently degrade antibiotic organic pollutants in water. However， its wide application is limited by the large amount of iron sludge， the difficulty of Fe²⁺ regeneration and the problems of secondary pollution. The electro-Fenton technology combines electrochemistry and the Fenton oxidation process to significantly improve the efficiency of H₂O₂ activation. The use of cobalt-based metal organic frameworks（Co-MOFs） as electric Fenton catalysts has high catalytic activity and stability， which can avoid the generation of iron sludge and achieve the purpose of efficient degradation and removal of antibiotic organic pollutants in water. In this paper， Co-MOFs nanocrystalline materials were grown in situ on carbon fiber electrodes， and heterogeneous electric Fenton systems were constructed with the composite material as the cathode and platinum sheets as the anode. By adjusting the preparation method， the type of ligand， the ratio of ligand to metal， the calcination temperature， the system voltage， and the amount of H2O2 added， the optimal preparation conditions were explored： under the hydrothermal condition， Co-MOFs were synthesized by 1∶1 coordination of terephthalic acid and cobalt salt， which were grown in situ on a carbon fiber substrate， and calcined and activated under 100 ℃ in air. The optimal reaction conditions are： the voltage was -0.8 V and the H2O2 addition was 60 μL， and the degradation effect of tetracycline was 91% in 90 min.

Fabrication of High-reflectance and Low-thermal-conductivity HGM@TiO₂@ZnO Core-shell-shell Material via Rotational Coating QI Wenjia, ZHAO Kaiqing, WU Gang, WUMAIER·Yasen , TONG Gangsheng Chem. J. Chinese Universities    2025, 46 (11): 20250185-.   DOI: 10.7503/cjcu20250185 Abstract （538）   HTML （23）    PDF（pc） （5376KB）（323）       Knowledge map    Save Hollow glass microspheres（HGM） was utilized as the substrate and sequentially was coated with eggshell-like TiO₂ and needle-like nano-ZnO through a rotational coating process and a two-step heterogeneous precipitation method， constructing a high-reflectance， low-thermal-conductivity core-shell-shell material HGM@TiO2@ZnO. Research demonstrates that the obtained HGM@TiO₂@ZnO exhibits a hollow core structure that reduces heat transfer efficiency. The dual-shell structure， comprising high and low refractive index layers， induces multi-level reflection and scattering of light， while the cavity structures formed between the needle-like nano-ZnO further decrease the thermal conductivity of HGM@TiO₂@ZnO， achieving a dual synergistic effect of "reflection-thermal insulation". Results indicate that the HGM@TiO₂@ZnO material achieves an average solar reflectance up to 88.64% in the visible-near-infrared（380—2500 nm） range， representing improvements of 25.6%， 6.2%， and 10.0% compared to HGM， HGM@TiO₂， and physically blended material HGM&TiO₂&ZnO， respectively. When HGM@TiO₂@ZnO was added to an acrylic resin matrix at volume fraction of 40%， the resulting coating exhibited an average solar reflectance of 72.86% and a thermal conductivity as low as 0.08 W·m-1·K-1. Compared to coatings with the same volume fraction of HGM added to the acrylic resin， the reflectance increased by 5.4%， while the thermal conductivity decreased by 34%. Thus， this study elucidates the synergistic regulation mechanism of the core-shell-shell hierarchical structure on photothermal performance， providing theoretical support and material foundations for the development of high-efficiency thermal-reflective and insulating functional coatings.

Comprehensive Analysis of the Gene Expression Status in Wild and Drug-resistance Cell Lines of Colorectal Cancer YU Chengkun, ZHOU Haichao, ZHANG Congmin, REN Yan, LIU Siqi Chem. J. Chinese Universities    2025, 46 (8): 20250049-.   DOI: 10.7503/cjcu20250049 Abstract （532）   HTML （5）    PDF（pc） （3592KB）（64）       Knowledge map    Save This study examined 3 colorectal cancer cell lines， HCT116， LoVo， and HT29， each of which contained both wild-type and Oxaliplatin/SN38-resistant strains. Transcriptomic and proteomic analyses were performed. By analyzing the differential gene expression between wild-type and resistant strains， it was found that the transcriptomic patterns of HCT116 and LoVo wild-type cell line appeared similar， whereas both were different from HT29. In view of different expression genes（DEGs） of the cell lines responding to oxaliplatin or SN38， the transcriptomes of wild cell lines were different from that obtained from the drug resistant cell lines. Moreover， among oxaliplatin resistant cell lines， the transcriptomic responses were consistent， but in SN38 resistant cell lines， the relevant changes were complicated， particularly in HT29 cells. Based on comparison of different expression proteins（DEPs） in these cells， DEPs were overlapped with DEGs somehow. In contrast to transcriptomes， the protein abundance in Lovo and HT29 was sensitively impacted by drugs， while the functional clustering derived from DEPs in LoVo and HCT116 was comparable. By analyzing the commonly regulated genes in both the transcriptome and proteome， we identified candidate drug resistance-related proteins. Specifically for drugs， the abundance responses of proteins in these cell lines initiated by oxaliplatin were significantly lower than these induced by SN38. Taking all analysis to gene expression status in wild and drug resistance cell lines together， this study indeed sets up a solid dataset to explore the molecular mechanism of drug resistance and provides an omic clue in colorectal cancer research.

Fabrication of ZIF-67-Derived Hollow Flower-like Ni0.3Co2.7S/MoS2 Composite Catalysts for Hydrogen Production via Water Electrolysis LI Dong, PU Xue, DENG Li, WU Qilin, JU Anqi Chem. J. Chinese Universities    2025, 46 (9): 20250144-.   DOI: 10.7503/cjcu20250144 Abstract （518）   HTML （22）    PDF（pc） （6506KB）（109）       Knowledge map    Save Hydrogen energy， as one of the most promising clean energy vectors in the 21st century， has positioned its efficient production technology as a critical pathway for global energy transition. However， large-scale implementation of water electrolysis remains constrained by the high overpotentials of hydrogen evolution reaction（HER） and oxygen evolution reaction（OER）， resulting in inefficient energy conversion. Although noble-metal-based catalysts（Pt， IrO2/RuO2） exhibit exceptional catalytic activity， their scarcity and prohibitive costs severely restrict industrial deployment. Transition metal sulfides（TMS） have emerged as competitive alternatives to noble-metal catalysts due to their cost-effectiveness and tunable electronic structures， yet their inferior intrinsic activity hinders large-scale applications. Metal-organic frameworks（MOFs）， featuring ordered porous architectures， high specific surface areas， and uniformly distributed metal nodes， can be converted through controlled sulfurization into cobalt-based sulfides with hierarchical porosity. This conversion not only preserves the three-dimensional skeletal advantages of the precursors but also effectively modulates the density of states at metal centers via sulfur-atom doping. In this work， NiCo ZIF-67 is employed as a precursor to construct a hollow-structured Ni0.3Co2.7S/MoS2 flower-like composite catalyst through sulfur-induced Kirkendall effect-driven synthesis. The hollow framework of the composite synergistically enhances cycling stability by effectively anchoring MoS2 nanosheets， while its expanded interlayer spacing facilitates sufficient electrolyte infiltration and optimizes charge transfer pathways. The Ni0.3Co2.7S/MoS2 catalyst demonstrates exceptional electrocatalytic hydrogen evolution performance， achieving a low overpotential of 150 mV at 10 mA/cm2. Remarkably， after galvanostatic stability testing（80 h at 10 mA/cm2） and 2000 cyclic voltammetry cycles， the overpotential increases by only 7 mV， highlighting its superior activity and long-term durability. This study provides a novel strategy for designing efficient and stable TMS-based electrocatalysts for water splitting， offering significant scientific value for advancing green hydrogen technologies.

Chinese Universities    2025, 46 (10): 20250214-.   DOI: 10.7503/cjcu20250214 Abstract （514）   HTML （76）    PDF（pc） （5046KB）（175）       Knowledge map    Save Hydrolysis in alkaline condition and inferior temperature resistance property were two disadvantages of SrAl2O4∶Eu2+，Dy3+（SrAl2O4） long persistence phosphors. To address these two issues， this study employed ethylene glycol as a non-aqueous reaction medium to cover a SiO2 layer on the SrAl2O4 surface. This strategy effectively isolated the SrAl2O4 matrix from water molecules， hence avoiding the side hydrolysis reactions during the coating process. After careful study， the optimized coating process was determined as follows： solution pH value was 11.0， reaction temperature was 80.0 ℃， reaction time was 2.0 h， Na2SiO3 dosage（mass） was 6.0% of SrAl2O4 powders. Under the optimized condition， a dense SiO2 layer with the thickness of 60 nm was seamlessly coated on SrAl2O4 surface， leading to a SrAl2O4@SiO2 core@shell composite. According to X-ray diffraction pattern， the crystal phase of the SrAl2O4 was not changed during the coating process. Compared to the pristine SrAl2O4， the luminescence intensity of composites was only reduced 11.2%， while the anti-hydrolysis property was largely improved. In practical application， the bright green color could be easily observed by naked eyes after the composite was washed for 6 h in the presence of detergent. The thermogravimetric analysis indicated the remained weight of SrAl2O4@SiO2 composites was 93.7%（mass fraction） after calcinated at 800 ℃. This study provided a novel way to improve the anti-hydrolysis property and high-temperature resistance property of SrAl2O4 without remarkably sacrificing their luminescence property， and this is beneficial for their real application in fire protection.

Research Progress of MOF-SACs in Water Splitting for Hydrogen Evolution Reaction HE Yutong, LI Hanxi, FAN Xiaoyan, YU Meihui, ZHANG Jijie Chem. J. Chinese Universities    2026, 47 (3): 20250333-.   DOI: 10.7503/cjcu20250333 Abstract （499）   HTML （44）    PDF（pc） （10493KB）（30651）       Knowledge map    Save The hydrogen evolution reaction（HER） from photocatalytic and electrocatalytic water splitting is a pivotal technology of future green hydrogen economy， but the synthesis of low cost， high efficiency catalysts with high stability remains a critical scientific challenge to be addressed for both. Single-atom catalysts（SACs） are regarded as one of the most promising catalysts due to their unique electronic structure and maximum atomic utilization. The metal-organic framework materials（MOFs） are ideal single atoms carriers due to ultra-high specific surface area， tunable porous nanostructure， and abundant active sites， serving as SACs synthesis precursors owing to their unique pyrolysis characteristics. The composite system of MOFs and single atom catalysts（MOF-SACs） can take full advantage of the synergistic effect， thus improving the hydrogen evolution catalytic activity significantly. In this review， the recent applications and research progress of MOF-SACs in photocatalytic and electrocatalytic water splitting for hydrogen production progress are introduced， while the strategies for enhancing the catalytic activity are summarized. Moreover， the future research hotspots and trends are outlined， which can provide novel design models for HER catalysts. Table and Figures | Reference | Related Articles | Metrics
