Both MoO₃ and V₂O₅ exhibit considerable absorption in the visible region as seen from their UV-visible diffuse reflectance spectra. In view of higher absorption of V₂O₅ compared to MoO₃, the present study is tken up to see whether addition of V₂O₅ will improve the visible light photocatalytic activity of MoO₃. 25 wt% V₂O₅ in MoO₃ showed the highest efficiency and degraded Methyl orange, Rhodamine-B and Eosin Y completely in 30, 160 and 40 mints respectively, while Methylene blue is only partially degraded.
