Abstract

Bi2WO6 a visible light photocatalyst is synthesized by solid-state metathesis reaction between BiOCl and Na2WO4 as precursors. X-ray diffraction pattern of ground homogenized mixture of precursors heat treated at 600 °C for 4 h and washed free from byproduct NaCl indicated formation of phase pure Bi2WO6. Photocatalytic activity of Bi2WO6 powder is evaluated in terms of photocatalytic degradation of methyl orange and congo red under visible light irradiation, presence of external oxidant is found enhance the rate of degradation in both cases. Formation of •OH free radicals during irradiation is ascertained through scavenger D-manitol.
