Study on the Preparation of WO₃/TiO₂ Composite Photocatalyst and its Photocatalytic Activity

Abstract:

WO3/TiO2 composite photocatalyst was prepared from tetrabutyl titanate, ammonium tungstate by sol-gel method. The influence of acetic acid and ethanol on the gel point time, and the influence of doping amount of W on the photocatalytic activity was studied. The properties of powders were characterized by Fourier transform infrared spectrometer(FT-IR), and the photocatalytic activity was characterized by probe reaction of methyl orange degradation. The results show that the homogeneous transparent precursor is prepared at the amount of acetic acid =1mL and the amount of ethanol =10mL.When the doping amount of W reached to 0.12%, the best photocatalysis efficiency was obtained. Under the experimental conditions, the infrared absorption band of the W－O was not observed.
