Summary: As an attractive semiconductor photocatalyst, (CuInS2)x-(ZnS)y has been intensively studied in photo-catalysis, due to its unique layered structure and stability. In this study, a series of CuxIn0.25ZnSy photocatalysts with different trace Cu+-dominated ratios were synthesized. It was found that doping with Cu+ ions can increase the valence state of In and induce a distorted S structure, resulting in a decrease in the semiconductor bandgap. The optimized Cu0.04In0.25ZnSy photocatalyst with a bandgap of 2.16 eV showed the highest catalytic hydrogen evolution activity (191.4 lmol.h-1) when the doping amount of Cu+ ions was 0.04 atomic ratio to Zn. Rh loaded Cu0.04In0.25ZnSy showed the highest activity among common cocatalysts, with an apparent quantum efficiency of 49.11% at 420 nm and a rate of 1189.8 lmol center dot h-1. The internal mechanism of photogenerated carrier transfer between semiconductors and different cocatalysts was also analyzed by the band bending phenomenon.
