Uniform and crack-free TiO2 thin films with highly-dispersed platinum were p repared from i-PrOH-TTIP-DEA-H2O system containing H2PtCl6*6H 2O as metal source by sol-gel method. The microstructure and morphology of th e films were characterized by TEM and XRD respectively. It was found that the Pt particles dispersed in the films and had a homogeneous distribution in the shap e of sphere with an average size of about 5 nm. This study also showed that the doping with few percent of Pt resulted in the formation of pure rutile phase at a temperature as low as 550 ℃, whereas the same pure phase was formed at the te mperature higher than 650 ℃ in TiO2 or Au/TiO2 thin films.
