摘要：

TiO2 nanoparticles with a diameter of 2-5 nm were prepared by reverse micelle method and characterized by TEM, DSC and XRD. The loaded nanosize TiO2 photocatalyst supported by small-porous molecular sieve HZSM-5 was obtained by impregnating method and identified by FTIR, Langmuir, BET and BJH adsorption. The synthesized pure TiO2 nanoparticles and loaded nanosize TiO2 were respectively used as photocatalyst to degrade K2Cr2O7 in aerated solution. The UV-Vis spectra indicated that the photocatalytic activity of the loaded TiO2 nanoparticles was higher than that of the pure.
