摘要：
Hydrogen energy is a kind of renewable energy with great potential due to its high energy density and environmental friendliness. It can effectively alleviate and even solve the global climate challenges caused by traditional fossil energy. Solar photocatalytic hydrolysis is an ideal method for hydrogen production, and photocatalytic catalyst is the core of research in this field. This paper introduces the research status and progress of TiO2, CdS and g-C3 N4, the 3 typical and promising single-phase catalytic materials, and summarizes the characteristics and modification methods of each catalyst. By changing the surface morphology or dopig with other substances, it can effectively improve the solar utilization and suppress the recombination of photogenerated electron/hole pairs, and thus improve the photocatalytic activity and stability. But eventual industrialisation is still a long way off. At last, the problems faced by photocatalysts for hydrogen production were pointed out and the future research directions were prospected, which provided reference for the design of efficient and stable photocatalysts in the future. © 2021, Chemical Industry Press Co., Ltd..
