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.
