Preparation and Characterization of WO_3-TiO_2 Film Composite Photocatalyst in Ultrasonic Filed AITranslate
Abstract AITranslate
The nano-crystal composite WO3-TiO2 photocatalyst is prepared by sol-gel process in ultrasonic filed. Study is made of the effects of ammonium tungstate dosage,number of film coatings, sintering temperature and duration, various substrates,pH value,dissolved oxygen and the ultrasonic on the photocatalyric activity in the light of the film photo-degradation of rhodamine B. The results show that when compared with conventional sol-gel process,in the untrasonic field the gelating time of the sol is remarkably shortened, the particle size of the photocatalyst diminishes evidently and the photocatalytic activity increases significantly. The highest photocatalytic activity of WO3-TiO2 film is obtained with ammonium tungstate 0.5 % （mass）, the porous Ti plate as sub strate, 9 layers of film coating, 1 h sintering at 575℃. resulting in the WO3-TiO2 film almost all of rutile TiO2.
