Preparation of TiO2 Film on Stainless Steel Webnet and the Degradation of Formaldehyde

Abstract

Abstract: Photocatalytic titanium dioxide films coated on stainless steel webnet were prepared by a sol-gel route. SEM, XRD and TG-DTA were employed to characterize the samples. The effects of the films prepared with different proceedings on photoactivity were investigated by formaldehyde photodegradation, such as the molecular weight of PEG, the amount of PEG, moisture content, the thickness of the films and the annealing temperatures. The formaldehyde photodegradation ratio can reach above 90% by the TiO₂-based films. XRD patterns and SEM observation indicate that the TiO₂ films with mesoporous structure are composed of mixed rutile and anatase crystals.

Key words: sol-gel route, titanium dioxide films, formaldehyde, photocatalysis
