Studies on Nanometer TiO2 Film Photocatalyst Supported on Stainless Steel Wire Gauze

Abstract

Abstract: Nanometer TiO₂ film photocatalyst on stainless steel wire gauze was prepared by using sol-gel method. The structure of the TiO₂ film on stainless steel wire gauze was characterized by SEM, TEM, AES and Raman techniques. The effects of dipping time, the concentration of PEG and calcining temperature on the photocatalytic activity of TiO₂ film were studied. The best photocatalyst was obtained when sol contained 10%(molar fraction) PEG 400 and the film was calcined at 400 ℃.

Key words: TiO₂, Film, Photocatalysis, PEG, Raman spectrum
