TiO2 Mesoporous Film Photocatalyst Supported on Glass Beads

Abstract

Abstract: TiO₂ mesoporous films with aperture in about 4-5nm as photocatalyst on glass beads were synthesized by using the sol-gel method with TBT as the precursor and PEG400 as the template and characterized by SEM, TEM, AES and Raman techniques. The effects of Dipping time, the concentration of PEG and calcining time on the photocatalytic activity of TiO₂ film were studied on the evaluating equipment designed by ourselves. The best photocatalyst can be obtained when the sol containing 15% PEG 400 and the film about 210nm thick and calcined at 400℃ for 2h.

Key words: TiO₂, mesoporous film, glass beads as substrate, formaldehyde, photocatalysis
