Abstract:
Remarkably high photocatalytic activity for the overall H2O splitting, where the activity was 32 mmol h(-1) for H2 production and 16 mmol h(-1) for O2 production under irradiation from a 450 W high-pressure Hg lamp and the apparent quantum yield (AQY) was 71% under irradiation at 254 nm, was achieved by utilizing a Rh(0.5)Cr(1.5)O3(Rh; 0.5 wt%)/Zn(3 mol%)-Ga2O3 photocatalyst when Ga2O3 was prepared using dilute CaCl2 aqueous solution having a concentration of 0.001 mol l(-1).
