Enhanced Z-schematic water splitting using a (CuGa)0.5ZnS2 H2-evolving photocatalyst with treatment in aqueous solutions

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.
