Fig. 1From: A Facile Method for Preparation of Cu2O-TiO2 NTA Heterojunction with Visible-Photocatalytic ActivitySchematic structural diagram of Cu2O-TiO2 NTA heterojunction. Under visible light illumination, the electrons were excited to the conduction band of Cu2O particles and then transferred to the conduction band of TiO2 for the matching band gap structureBack to article page
