This experiment uses the sol-gel method to make Al3+mixed with the nanometer TiO2 photocatalyst. Through using the subunit blue as the pollutant, this paper studies the effect of the Al3+ doping on the photocatalytic performance of TiO2 under the high pressure mercury lamp of the 160 watts and the surface features of Al3+-TiO2 is measured by XRD. The results indicate that the doping of Al3+can enhance its photocatalytic activity and the optimized preparation conditions of the Al3+-TiO2 are as follows: the Al3+doping can improve the photocatalytic performance; the best preparing condition of Al3+-TiO2 is to use the aluminum nitrate as the precursor for the doping; r(Al:Ti) is equal to 0.01; the best photocatalytic activity is under 500 degrees celsius of the calcination temperature.
