Remarkably high apparent quantum yield of the overall photocatalytic H2O splitting achieved by utilizing Zn ion added Ga2O3prepared using dilute CaCl2solution

Remarkably high photocatalytic activity for the overall H₂O splitting was achieved by utilizing a Rh_0.5Cr_1.5O₃(Rh; 0.5 wt%)/Zn(3 mol%)–Ga₂O₃photocatalyst when Ga₂O₃was prepared using dilute CaCl₂aqueous solution (0.001 mol l⁻¹).
