Mesh of TiO2/graphene/Cu2O was fabricated by chemical vapor deposition of graphene following electrochemical deposition of Cu2O on anodized Ti soft wire bearing TiO2 nanotubes. The mesh of TiO2/graphene/Cu2O was applied in photoelectrocatalytic oxidation of bisphenol A (BPA). The as-prepared TiO2/graphene/Cu2O mesh was used as both catalyst and electrode. Under visible light irradiation, BPA was effectively oxidized through photoelectrocatalysis over the TiO2/graphene/Cu2O mesh. Three main intermediates were evidenced during photoelectrocatalytic degradation of BPA, and no toxic products were determined. A detailed pathway of BPA degradation by TiO2/G/Cu2O is proposed based on the identified intermediates. (C) 2015 Elsevier B.V. All rights reserved.
