Photocatalytic degradation of aniline is studied over H2O2 sensitised monoclinic BiVO4 under visible light irradiation. Combination of BiVO4+H2O2 showed a synergetic effect in enhancing the rate of degradation. Formation of more. OH free radicals during irradiation in presence of H2O2 is ascertained by photoluminescence spectra using terpthalic acid as probe molecule.
