Title
Photocatalytic degradation of bisphenol A by Ag3PO4 under visible light
Abstract

Ag3PO4 catalysts exhibited excellent photocatalytic performance in the degradation and the mineralization of bisphenol A, displaying considerably higher photocatalytic activity than N–TiO2 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 Ag3PO4 surface, along with a two-electron reduction of dissolved oxygen to H2O2.

Graphical abstractAg3PO4 catalysts exhibit excellent photocatalytic performance in the degradation and mineralization of bisphenol A under visible-light irradiation. The degradation mechanism mainly occurs through direct hole oxidation and the concurrent two-electron reduction of dissolved oxygen to H2O2.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► Ag3PO4 photocatalyst is firstly applied to the degradation of bisphenol A. ► Ag3PO4 shows excellent photocatalytic performance and higher activity than N–TiO2 under visible light. ► The Ag3PO4-catalyzed degradation of bisphenol A mainly results from direct hole oxidation. ► The concurrent reduction of dissolved oxygen to H2O2 occurs via two-electron reduction.
