Photocatalytic degradation of bisphenol A by Ag3PO4 under visible light

Abstract Ag 3 PO 4 catalysts exhibited excellent photocatalytic performance in the degradation and the mineralization of bisphenol A, displaying considerably higher photocatalytic activity than N–TiO 2 under visible light (λ > 420 nm). The trapping effects of different scavengers and spectrophotometric results proved that the oxidation of bisphenol A mainly occurred at photogenerated holes on the Ag 3 PO 4 surface, along with a two-electron reduction of dissolved oxygen to H 2 O 2 .
