Abstract: In recent years，the research of photocatalysts of splitting water under visible light irradiation has attracted much attention，especially the preparation and modification of novel photocatalyst. Recent advance in photocatalytic hydrogen production was reviewed，and the preparation methods of photocatalysts were discussed，such as ion-doping，solid solution，composite semiconductor and co-catalyst. Based on the analysis above，lower utilization ratio of visible light and photochemical conversion efficiency were the most serious problems，and developing efficient and novel photocatalysts and studying the mechanism would be necessary.
