The morphology and structure were obtained through SEM， which showed that the structure of the CBWO-60 was cuboid rod-like morphology and nanosheet. The EDS elemental mapping images displayed that Cu， W， Bi and O elements were evenly dispersed in CBWO-60. The crystalline phases and molecular structures of the catalyst were determined by XRD and FTIR. These results firmly confirmed that the successful synthesis of the composite. The large specific surface area of CBWO-60 was investigated via BET. XPS analysis proved that the Cu+ and Cu2+ coexisted， which promoted the cycling of Fenton reaction. Moreover， the displacement of binding energy well verified the strong electronic interaction rather than a physical contact between CuBi2O4 and Bi2WO6 in the heterojunction. The band structure of the heterojunction was proved by UV-Vis DRS and VB-XPS analysis. The interface charge transfer situation of the heterojunction was investigated by PL， EIS， and transient photocurrent response spectra. In a series of catalysts， CBWO-60 has the highest degradation efficiency for Ciprofloxacin（CIP） in the photo-electro- Fenton-like（PEF-like） system， with a degradation efficiency of 98.0% at 90 min. At the same time， when the initial pH of the solution was in the range of 2—6， the system could always maintain effective CIP removal efficiency. The pH range of this system was broadened to some extent compared to the conventional Fenton method. In the PEF-like system， CBWO-60 showed high catalytic activity to quinolone， sulfonamides and tetracycline antibiotics， which proved the universality of CBWO-60. Finally， the degradation efficiency of CIP still maintained 87.8% after five cycles of experiments， and the crystal structure of CBWO-60 remained unchanged after the reaction. Based on the results of HPLC-MS， five possible pathways for CIP degradation were proposed. This study provided a new idea for the purification and treatment of antibiotic pollution in the water environment. Table and Figures | Reference | Related Articles | Metrics

Chinese Universities    2024, 45 (2): 20230442-.   DOI: 10.7503/cjcu20230442 Abstract （557）   HTML （16）    PDF（pc） （3974KB）（2885）       Knowledge map    Save This study employs an environmentally-friendly method to synthesize MIL-100（Fe）， and utilizes a double-solvent impregnation approach to confine Pt nanoparticles within the pores of MIL-100（Fe）， subsequent to acidification with HCl and reduction with formaldehyde， a bifunctional catalyst， Pt/MIL-100（Fe）， featuring hydrogenation and Lewis acid centers， is prepared. The catalytic performance is evaluated using the selective hydrogenation of cinnamaldehyde（CAL） as a probe reaction. Under optimal conditions（60 ℃， 1 MPa H2）， the conversion of CAL reaches 88.3% in 2 h， with a cinnamyl alcohol（COL） selectivity of 84.9%. By comparing the reaction performance of Pt/MIL-100 catalysts with Cr， Al and Fe metal centers， it is revealed that the Fe center favors for the hydrogenation of C=O bonds in both CAL to COL and furfural to furfuryl alcohol. The impact of water content in the reaction system on the selective hydrogenation of CAL is extensively studied. Characterization and static adsorption experiments indicate that removal of free water from the pores of Pt/MIL-100（Fe） facilitates direct enrichment of CAL in the channels， leading to an enhanced conversion. Additionally， removal of coordinated water from the Fe cluster promotes the adsorption of the C=O group of CAL， resulting in an improved selectivity toward COL. After five catalytic cycles under optimal conditions， Pt/MIL-100（Fe） maintains the catalytic performance. Results of powder X-ray diffraction （XRD）， transmission electron microscopy （TEM）， and low-temperature nitrogen adsorption characterization confirm the stability of the catalyst structure after reaction.

The unclear thermal decomposition mechanism of DNTN has seriously hindered its application in propellants. The thermal decomposition process of DNTN was investigated by a combination of reactive force field molecular dynamics（ReaxFF MD） simulation， solid-phase in situ infrared spectroscopy（in situ IR） and TG-DSC- FTIR-MS simultaneous techniques， and the gas and solid products of the thermal decomposition were analysed， the thermal decomposition mechanism was elucidated. The results showed that the decomposition of DNTN was revealed that the process occurred in three stages. During the first stage from 127 ℃ to 147 ℃， the O—N bond in DNTN was partially broken， releasing a minor amount of NO2 gas. In the second stage， between 147 ℃ and 220 ℃， DNTN underwent rapid decomposition， removing the nitro groups and decomposing the quaternary carbon skeleton， accompanied by the formation and cleavage of the microcyclic structure， releasing a large amount of gases such as NO2 and CO2， and at the same time emitting a large amount of heat. The third stage， taking place within the temperature range of 240—350 ℃， involved the high temperature pyrolysis of the remaining solid product of DNTN， which resulted in a limited release of CO2 gas， and above 300 ℃， the remaining solid phase material would further react to result in the production of cyano. In this paper， the thermal decomposition mechanism of DNTN was illustrated from a multistage perspective， which had important guiding significance for its application in propellants and the follow-up research on stability mechanism.

A crucial step toward effective oil-water separation is the construction of a functional interface for selective separation of the oil-water mixture. In this paper， g-C3N4/TiO2-PVDF（polyvinglidene fluoride） photocatalytic membranes with different exposed crystal planes of TiO2 were prepared， and the effects of different exposed crystal planes on oil-water separation were studied.

Under visible light， the pure water flux of g-C3N4/TiO2（001）-PVDF membrane reaches 2002.9 L·m‒2·h‒1， which is 60.8% higher than that of g-C3N4/TiO2（101）- PVDF membrane， and 47.1% higher than that under dark conditions. Simultaneously， the rejection efficiency of the five kinds of oil substances is more than 99%， and the high permeation flux of 420.4—665.2 L·m‒2·h‒1 is maintained. The highest rejection efficiency of g-C3N4/TiO2（101）-PVDF membrane is only 61.8%， and the permeation flux is less than 200 L·m‒2·h‒1. The mechanism of different crystal planes was explored by transient photocurrent response and electron paramagnetic resonance technology. The results showed that the g-C3N4/TiO2（001）-PVDF membrane had a stronger light response current and more hydroxyl radical production. The permeation flux of g-C3N4/TiO2（001）-PVDF membrane was still 264 L·m‒2·h‒1 after a 360 min continuous experiment. High rejection efficiency and permeation flux were always maintained in the 8 cycles of regeneration experiments. Obviously， the photocatalytic membrane with exposed TiO2（001） has a greater permeability， selectivity， and stability， which is more appropriate for the effective separation of oil-water wastewater.
