V₂O₅/FeVO₄ photocatalysts were successfully epared prepared by one-step liquid phase precipitation. The photocatalytic activitied of the V₂O₅/ FeVO₄ series catalysts with different V₂O₅ contents were discussed. The as- prepared samples were character-ized by XRD, SEM and BET. Also the photocatalytic activity wasmeasured by means of photodegradation of methyl orange(MO) in the solution irradiated by visible light. It was found that the 3mol % V₂O₅/ FeVO₄ and calcinated at 800 for 4 h had the best ability of photo-degradation of MO, the degradation rate can increase18 or so than that of pure FeVO₄ after 12 h. Doping V₂O₅ can act as electron traps promoting the electron-hole separation and then in-crease the photo-activity.
