%X The Ag/TiO2 and Ni/TiO2 photocatalysts with variable Ag and Ni loadings were prepared by the sol-gel method, and their photocatalytic activities were tested by using gas-phase toluene degradation as the modal reaction. Two doped photocatalysts were characterized by means of transmission electron microscopy (TEM), X-ray diffraction (XRD) and fluorescence spectra (FS). The results showed that a suitable metal ion loading could greatly enhance the TiO2 photocatalytic activity, and Ni/TiO2 was superior to Ag/TiO2. The optimal doping amount of two photocatalysts was 0.4%. At the same time, the effect of doped metal ion loadings on the photocatalytic activity was discussed.
