STUDY ON THE PREPARATION OF NANO SIZED TiO2/Si THIN FILMS AND THEIR PHOTOCATALYTIC PROPERTIES

doi:10.7517/j.issn.1674-0475.1997.03.232

Abstract

Abstract: In this paper, TiO₂/Si and TiO₂/glass thin films with nano-crystalline have been prepared by the sol-gel processing of controlled Ti alkoxide hydrolysis. Their photocatalytic properties are also examined at the same time. The results indicate that by selecting substrates and annealing temperature the size of thin films can be controlled. The particle size effect and the thickness of films have effects on the photocatalytic activities of the thin films. Moreover, photocatalytic thin films can be re-used.

Key words: TiO₂, Photocatalysis, film, sol-gel processing
