Development of Z-Scheme Photocatalyst Systems Combining Nonmetal Oxide Materials for Water Splitting under Visible Light Irradiation: (CuGa)0.5ZnS2 as a H2-Evolving Photocatalyst and TaON as an O2-Evolving Photocatalyst
Water splitting under visible light irradiation using a Z-scheme system combining nonmetal oxides of TaON and (CuGa)0.5ZnS2 is demonstrated. The key factors lie in coloading with Ir and CoOx cocatalysts on TaON and using reduced graphene oxide (RGO) as a solid-state electron mediator. Ir is loaded by an impregnation method, while CoOx is loaded by either impregnation or photodeposition methods. Loaded Ir boosts the electron migration from TaON to RGO, and loaded CoOx works as an active site for O2 evolution. Photocatalytic reduction of graphene oxide to RGO accompanied by simultaneous oxidation of Co2+ ions to CoOx over Ir-loaded TaON is the optimum process for the formation of an RGO-(CoOx/Ir/TaON) composite.
