Preparation and Characterization of Nanometer TiO_2-SnO_2 Composite Photo-catalyst

Jin‐Tang Wang

Abstract

Nanometer TiO_2-SnO_2 photo catalyst was prepared from SnCl_4·5H_2O and Ti(SO_4)_2 by an activated surface method. The morphology and structure were investigated by XRD,XPS,TEM and BET method. The nanometer TiO_2-SnO_2 catalyst was composed of anatase TiO_2 and rutile SnO_2. The nanometer particles were spherical and their size was about 10 nm.
