Abstract: Aseries of SO42-/TiO2-SiO2 catalysts with different mass fractions of SiO2 were prepared by sol gel method. The effect of adding SiO2 on the crystal structure, specific surface area, oxygen adsorption, and acidity of SO42-/TiO2 catalyst and its photocatalytic property for degradation of bromomethane was studied. The results showed that the specific surface area and amount of oxygen adsorption of catalyst were increased by addition of SiO2, leading to the obvious increase on photocatalytic activity of SO42-/TiO2-SiO2 catalysts and mineralization ratio of bromomethane. Comparing with SO42-/TiO2, the acidic strength and anti moisture ability of SO42-/TiO2-SiO2 catalyst were decreased.

Key words: Photocatalytic performance, Solid superacid, SO42-/TiO2-SiO2
