Preparation of Fluorine Doped TiO2 Photocatalysts and its Photocatalytic Activities under Simulate Sun's Rays
F-doped TiO2 catalysts were obtained by sol process，in which tetrabutyl titanate was used as precursor and hydrofluoric acid as iondonors. The photodegradation experimental results showed that photoeatalytic activity of the F-doped catalyst is higher than that of the un-doped ones，the F-doped catalyst with 1:4(F:Ti molar ratio) fluorine at 40 was the highest catalytic efficiency under simulant sun's rays irradiation. The doped catalysts in anatase phase own higher photocatalysis characterized by XRD and BET. Effects of properties on the F-doped TiO2 catalysts were developed.
