Photocatalytic degradation of Brilliant green, Orange G and Crystal violet dyes is investigated under visible light irradiation using Bi2MoO6 synthesised by coprecipitation and calcined at 4500 C for 20 h. Addition of H2O2 is found to enhance the rate of degradation. The above dyes are degraded for 210, 180 and 60 min of irradiation, respectively. Formation of .OH free radicals during irradiation is ascertained by means of photoluminescence studies using Terephthalic acid as probe molecule. A possible mechanism for photocatalytic degradation is suggested.
