摘要:

光催化分解水是将太阳能转化为化学能的有效手段之一. 相比于粉末光催化, 采用H型电解池的光 电催化方法具有材料选择范围大、 载流子迁移和分离效率高、 电极易于回收等优点. 近年来, 金属有机框架 材料(MOFs)在光电催化水分解领域得到越来越多的应用. 相比于传统无机催化剂, MOFs光电极具有比表面积大、 结构易于调控等独特优势. 本文按照MOFs的应用形式分为纯MOFs、 MOFs与其它催化剂的复合结构和MOFs衍生物3类, 总结了近年来MOFs在光电催化水分解领域的研究现状和进展, 介绍了光催化/电催化领域的部分典型研究成果, 最后讨论了MOFs在光电催化水分解领域研究的重点和热点, 并对其未来发展做出了展望.

Abstract:

Photoelectrochemical water-splitting has been considered as one of the most efficient methods to convert solar energy into chemical energy. Compared to the photocatalytic system with powder photocatalyst, the photoelectrochemical system using an H-type electrolytic cell possesses advantages of wider material selection range, higher charge transfer and separation efficiency, and easier ways to recycle photocatalysts. In recent years, more and more researches focus on applying metal-organic frameworks(MOFs) as the photoelectrodes in photoelectrochemical water-splitting reactions. Compared to inorganic photocatalysts, MOFs semiconductors exhibit large surface areas and tunable structures, which are beneficial to photocatalysis. In this review, we summarized research status and progress of MOFs in photoelectrochemical water-splitting applications according to the classification of MOF-based photoelectrode, including MOFs photoelectrode, MOFs-based heterostructure photoelectrode and MOFs-derived photoelectrode. This review also covers some typical research cases in the field of photocatalysis, which provides references for the research of MOFs in the field of photoelectrochemical water-splitting. Finally, research trends and hotspots in this field are also discussed.
