The Photocatalxtic Properties of Cu2+ Doped ZnO Nano Material
Cu2+ doped ZnO nano material has been prepared by electrochemical deposition method and the formation mechanism of the material has been explained by two step growth process. The charac-teristics of Cu2+ doped ZnO nano material has been analysed by using the X-ray powder diffraction (XRD), the scanning electron microscope (SEM) and the electron probe energy spectrum (EDS). The results show that the morphology and grain size of ZnO nano material could be regulated by doping Cu2+ and also the photocatalytic performance of ZnO was changed. The results of methyl orange photocatalytic degradation show that the photocatalytic performance of Cu2+ doped ZnO was improved by doping moderate Cu2+ and the photocurrent density of doped ZnO was three times of pure ZnO at the same condition, when the concentration of Cu2+ was 1 × 10−4 mmol/L.
