| 英文摘要 | the tio2 thin films from dip-coating system were magnetron sputtered on with wox, and can be activated by visible-light in gaseous dimethyl benzene photocatalytic degradation. the mechanism of its visible-light activity was investigated by uv-vis absorption spectra and x-ray photoemission. uv-vis absorption spectra showed its visible-light response expanding and having strong absorption with respect to the pure tio2 film. xps indicated the formation of w impurity energy level and ti defect energy level, which was the main reason for the absorption in the visible-light range and the perquisite to have visible-light activity; and made fermi level upper moved, free carriers more and photocatalytic efficiency enhanced. |
