Abstract
ZnO/SnO2 nanocomposite powder were prepared by coprecipitation method with SnCl4·5H2O, ZnNO3·6H2O, HCl, NaOH as raw materials. Influence of different mol ratio of ZnO/SnO2 on the photocatalytic activity of ZnO/SnO2 nanocomposite powder was researched by the degradation of methyl orange as a reaction model. The particle size and dispersion of ZnO/SnO2 powder was characterized by transmission electron microscope(TEM). The results show that the photocatalytic activity of ZnO/SnO2 nanocomposite powder was increased significantly when compounded by SnO2, the photoactivating activity of ZnO/SnO2 powder starts increasing and then decreasing when the ratio of ZnO/SnO2 decreases. When ZnO:SnO2 is the ratio of 4:1(mol ratio)，the photocatalytic activity of ZnO/SnO2 nanocomposite powder is the best and the degradation rate of methyl orange is 42.09% when visible light illuminate for 225 minutes, particle size is 20-30 nanometer and dispersion is good.
