Photocatalytic O-2 evolution under visible light irradiation on BiVO4 in aqueous AgNO3 solution
BiVO4 with a 2.3 eV band gap showed an activity for Oz evolution from aqueous solutions containing Ag+ as an electron scavenger under visible light irradiation (lambda > 520 nm). The quantum yield was 0.5% at 450 nm.
