摘要：

Cu-doped nano-SnO2TiO2 gelatins were prepared and coated onto glass substrates by spin coating method, followed by drying at low temperature and calcined at high temperature. The films were characterized by XRD, SEM, EDS, and UV-Vis. The photocatalysis degradation efficiency was studied by using methyl orange as probe. XRD patterns show that the films are anatase structure. SEM images show that the surfaces of the films are flat without obvious crack, and the average diameter is about 20 nm. EDS results indicate that Cu has been introduced to SnO2/TiO2 films. UV-Vis absorption spectra show that the absorbance of Cu-doped SnO2/TiO2 films at visible region increase comparing to pure TiO2 film. The degradation experiment under UV light shows that the photocatalysis degradation efficiency of Cu-doped SnO2/TiO2 film is higher than that of pure TiO2 film. The photocatalysis degradation efficiency is the biggest when the doping mole fraction of Cu is 10%. ©, 2015, Chines Academy of Sciences. All right reserved.
