Photocatalytic CO₂ Reduction Using Water as an Electron Donor under Visible Light Irradiation by Z-Scheme and Photoelectrochemical Systems over (CuGa)_0.5ZnS₂ in the Presence of Basic Additives.

ABSTRACT: We demonstrated photocatalytic CO₂ reduction using water as an electron donor under visible light irradiation by a Z-scheme photocatalyst and a photoelectrochemical cell using bare (CuGa)_0.5ZnS₂ prepared by a flux method as a CO₂-reducing photocatalyst. The Z-scheme system employing the bare (CuGa)_0.5ZnS₂ photocatalyst and RGO-(CoO_x/BiVO₄) as an O₂-evolving photocatalyst produced CO of a CO₂ reduction product accompanied by H₂ and O₂ in a simple suspension system without any additives under visible light irradiation and 1 atm of CO₂. When a basic salt (i.e., NaHCO₃, NaOH, etc.) was added into the reactant solution (H₂O +
