Abstract

Five kinds of TiO₂ photo catalysts doped with Fe³⁺, Ag⁺, Eu³⁺, Ni²⁺, respectively, by Sol-Gel method from Ti(OC₄H₉)₄, were prepared to investigate different UV photo catalytic activity in the Ciba-Red aqueous solution. The effects of pH and the size of titania particles on the photo catalytic degradation rate of Ciba-Red aqueous solution were studied. TiO₂ doped with the bimetal ions, Fe³⁺ and Eu³⁺, showed best photo catalytic activity than other catalysts. The photocalytic degradation showed a quasi-first-order reaction kinetics. The mechanism of the photo catalytic degradation was also discussed.
