Abstract

The composite nanoparticles of un-doped, Fe-doped TiO2, Fe-N co-doped TiO2 were prepared by sol-gel method, and characterized by X-ray diffractomer, scanning electron microscope, and UV-Vis diffuse spectrometer. 2-methylisoborneol (2-MIB) was used as the model compound to investigate the photocatalytic activities of TiO2, and the effect of water quality on 2-MIB removal was also discussed. The results show that the prepared TiO2 was mainly anatase, and the band gap of TiO2 was narrowed and the absorption band moved to the visible direction after Fe3+-N3- doping. The best photocatalytic activity was achieved when 0.001% Fe-0.5% N co-doped TiO2 calcined at 500°C was employed, corresponding to the 2-MIB removal efficiency of 99.90% and pseudo-first order rate constant of 1.371 18 h-1 by photocatalytic oxidation process in 5h.
