Abstract
ZnO nanopowder doped with various amount Fe, nanometer ZnO/SnO2 powder and ZnO/SnO2 nanopowder doped with Fe were prepared by coprecipitation method with SnCl4 ?5H2O, ZnNO3?6H2O, HC1, NaOH, FeCl3?6H2O as raw materials. Influence of ZnO nanopowder doped with different content of Fe, different proportion of ZnO/SnO2 compound and ZnO/SnO2 nanopowder doped with Fe on the photocatalytic properties of ZnO nanopowder were studied by the degradation of methyl orange solution as a reaction model. ZnO nanopowder doped with different content of Fe was characterized by XRD. Nanometer ZnO powder was characterized by TEM. The results show that the photoactivating activity of ZnO nanopowder first increases and then decreases when Fe doping content increasing or the ratio of ZnO/SnO2 increasing, the photocatalysis activity of ZnO nanopowder increased significantly when modified by three kinds of modified methods, and the photocatalytic activity of Fe doped compounding modification nanometer ZnO/SnO2 is the best, the phase is ZnO and SnO2, the particle size is 15-20 nm, the dispersion of powder is better, specific surface area is 68.7 m2/g.关键词
