One-pot hydrothermal synthesis of noble-metal-free NiS on Zn 0.5 Cd 0.5 S nanosheet photocatalysts for high H 2 evolution from water under visible light

A series of Zn 0.5 Cd 0.5 S/NiS ( x mol%) composite photocatalysts have been synthesized. By optimizing the amount of NiS, the optimal ZCS/NS-5 composite photocatalysts achieved a superior photocatalytic H 2 evolution rate of 10 855.4 ± 461 μmol g −1 h −1 under visible light.
