Preparation of CuO/SnO_2 composite nanometer powder and photo-catalytic activity

HE Kai-ji,XING Rui,JIN Hui-gang,WANG Kai-ming(Nanometer Materials Research Center,University of Science and Technology Liaoning,Anshan 114051,China)  
The CuO/SnO2 composite nanometer powder is prepared with the liquid-phase precipitation method,and it is characterized with XRD and TEM.A photo-catalysis experiment is carried out,in which CuO/SnO2 is used as the catalysis with Methylene blue solution.The results indicate that it has the good dispersion,narrow particle size distribution,and a good light catalytic performance.The CuO/SnO2 composite nanometer powder with the CuO mass fraction of 70% has the best photo-catalysis effect by roasted 30 minutes in the temperature of 400 ℃.The mass concentration of 10 mg/L Methylene blue can be reached to 98.7% in 60 minutes.
