Preparation of TiO2/SnO2 and Photocatalytic Degradation of Dichlorvos over It
Abstract:
Nanoparticles of SnO2 coated with TiO2 have been prepared from Ti(OC4H9)4 and SnCl4·5H2O as precursors by an activated surface method. Their morphology and structures were investigated by IR, XRD, TEM and BET. The results indicated the nanometer TiO2/SnO2 was composed of anatase TiO2 and rutile SnO2. The TiO2/SnO2 showed a better catalytic activity than SnO2 and TiO2 alone in photocatalytic degradation of dichlorvos.
