Abstract:

The research of photocatalytic water splitting for hydrogen (H2) generation has been devoted a lot to the efficient utilization of solar energy and the development of hydrogen energy. The design of photocatalysts in photocatalytic hydrogen production is the key step of photocatalytic reaction. The preparation of outstanding and highly efficient photocatalyst is a vital point to improve the photocatalytic performance. In this review, the study of metal sulfides with hollow structures were comprehensively reviewed, including the preparation, application and further progress of the hollow materials. Further, the importance of hollow structure to increase surface area, enhance light absorption, accelerate charge separation and enhance reaction performance was analyzed. Herein, we propose the advantages and future development of hollow-structure in the development of photocatalysis, and provide a reference for the future design of novel photocatalysts, aiming to improve the utilization efficiency of sunlight and accelerate H2 evolution for the industrial applications of photocatalytic H2 generation.

Key words: solar energy, hydrogen production, photocatalysis, catalyst, sulfides, hollow-structure
