通过电化学沉积Cu 2 O和化学气相沉积石墨烯的方法，制备了TiO 2/graphene/Cu 2 O纳米网。将TiO 2/graphene/Cu 2 O网应用于双酚A（BPA）的光电催化氧化。将制备的TiO 2/石墨烯/Cu 2 O网用作催化剂和电极。在可见光照射下，TiO 2/graphene/Cu 2 O网对BPA进行了光电催化氧化。三个主要的中间体证明在光电催化降解双酚A，并没有有毒产物进行了测定。根据确定的中间产物提出了TiO 2/G/Cu 2 O降解BPA的详细途径。(C)2015爱思唯尔B. V.保留所有权利。
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.
