Effective visible light photodegradation of ortho and para- nitrophenols using BiVO4

A. M. Umabala

T Photocatalytic degradation of ortho- and para nitrophenols was investigated over BiVO₄ under visible light irradiation. BiVO₄ degraded ortho nitrophenol completely in 210 min. Rate of degradation enhanced in presence of H₂O₂ and complete degradation was achievd in 120min. Unlike ortho nitrophenol, para nitrophenol showed less photolysis and complete degradation of para nitrophenol was achieved for 120min of irradiation in presence of BiVO₄ and H₂O₂.
