High Performance Heterojunction Photocatalytic Membranes Formed by Embedment of Cu2O and TiO2 Nanowires in Reduced Graphene Oxide

Abstract

A heterojunction photocatalytic membrane consisting of Cu2O and TiO2 nanowires between reduced graphene oxide (rGO) sheets was fabricated by a facile process from colloidal suspension. The resultant membrane exhibits significantly enhanced activity under UV-Vis range, surpassing nanowires dispersions, owing to heterojunction formation and concurrent electron and hole transfer on rGO sheets. The membrane also possesses increased permeability and photocorrosion resistance. Such design and fabrication method of a rGO facilitated heterojunction photocatalytic membrane can be extended to a broad range of energy and environment applications.
