The weak electron-hole separation ability and the more severe photocorrosion of CdS largely limit its hydrogen precipitation performance. In this study, CoP loading on the surface of CdS was utilized to form a type I heterojunction. The photocurrent density increased from 2 & mu;A cm(-2) to 20 & mu;A cm(-2). When the loading of CoP was 10%, the best photocatalytic performance reached 4.43 mmolg(-1) h(-1) under visible light, which was 20.1 times higher than that of CdS (0.22 mmolg(-1) h(-1)). In addition, the loading of CoP solved the problem of CdS photocorrosion. After 5 cycles of simulated solar irradiation, the performance of 10% CoP/CdS remained at 93% of the initial test. This work provides new ideas for the design of low photocorrosion and high-performance catalysts.
