Transition metals (Cr,Fe,Ni and Zn) doped TiO2 nanoparticles were synthesized by sol-gel method using 2-hydroxyimidazole formate ionic liquid as microstructure control reagent.The prepared samples were calcined at 500 ℃,and then were characterized by BET,XRD and DRS,etc. The photocatalytic properties of the obtained TiO2 were also tested with Acid Blue 92 as simulated pollutants.The results show that transition metals doped TiO2 nanoparticles have a higher specific surface area and smaller particle size in comparison with those of pure TiO2,and the absorption spectrum of transition metals doped TiO2 shifts to visible light. According to the degradation of Acid Blue 92 in aqueous solution under UV irradiation,the photocatalytic activities of transition metal ions doped TiO2 nanoparticles are enhanced significantly.
