Study on Preparation of Nano-Grade TiO_2/SnO_2 Composite Particles by Sol-Gel Method

Xuri Li

Abstract

By incorporating stabilizing agent, catalyst into sol solution,TiO_2,SnO_2 and TiO_2/SnO_2 nano-crystalline powders were prepared by sol-gel method from inorganic and organic salts. The properties of particles were analysised by XRD,TEM,XPS and so on.The experimental results showed that TiO_2/SnO_2 was composed of nanometer anatase TiO_2 and rutile SnO_2 ,and the chemical activities of TiO_2/SnO_2 are better than those of SnO_2 and TiO_2.
