Abstract:
The effectiveness of the treatment of a (CuGa)0.5ZnS2 H2-evolving photocatalyst in an aqueous Na2S solution for Z-schematic water splitting under visible light irradiation is demonstrated. The treatment suppresses undesired consumption of photogenerated holes, including photocorrosion of (CuGa)0.5ZnS2.
