a Time courses of photocatalytic H2O2 generation over CoOx/Mo:BiVO4/Pd, Mo:BiVO4-CoOx-Pd, CoOx/Mo:BiVO4, Mo:BiVO4/Pd, and Mo:BiVO4. Reaction conditions: photocatalyst amount, 2 mg; reactant solution, 12 mL PBS aqueous solution (pH = 7.4) saturated with O2; light source, xenon lamp solar simulator, 100 mW/cm2, AM 1.5 G. We note the data series for CoOx/Mo:BiVO4 (7.5 μM at the reaction time of 60 min) overlap with those of Mo:BiVO4 (4.1 μM at the reaction time of 60 min). b Apparent quantum yield (AQY) of photocatalytic H2O2 generation over CoOx/Mo:BiVO4/Pd as a function of the incident light wavelength. Reaction conditions: photocatalyst amount, 2 mg; reactant solution, 5 mL PBS aqueous solution (pH = 7.4) saturated with O2; light source, monochromatic LED light. c Schematic of photocatalytic H2O2 generation over CoOx/Mo:BiVO4/Pd. CB and VB are short for conduction band and valence band, respectively.
