Enhanced Photocatalytic Performance under Visible and Near-Infrared Irradiation of Cu(1.8)Se/Cu(3)Se(2) Composite via a Phase Junction

A novel Cu(1.8)Se/Cu(3)Se(2) composite photocatalyst was prepared by the simple precipitation method. This composite possesses a wide photoabsorption until the range of near-infrared light, and exhibits significantly enhanced photocatalytic activity for methyl orange degradation under visible and ne...

description A novel Cu(1.8)Se/Cu(3)Se(2) composite photocatalyst was prepared by the simple precipitation method. This composite possesses a wide photoabsorption until the range of near-infrared light, and exhibits significantly enhanced photocatalytic activity for methyl orange degradation under visible and near-infrared light irradiation compared with bare Cu(1.8)Se and Cu(3)Se(2). The mechanism of this outstanding photocatalytic behavior can be explained by the calculated energy band positions. The efficient charge separation via a phase junction of Cu(1.8)Se/Cu(3)Se(2) composite would make a great contribution to its much-enhanced photocatalytic efficiency.
