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.
