A Novel Method for Preparing V-doped Titanium Dioxide Thin Film Photocatalysts with High Photocatalytic Activity Under Visible Light Irradiation



The liquid phase deposition (LPD) method was successfully used for preparing V-doped TiO2 thin film photocatalysts. In this simple and easily-controlled process, V-doped anatase TiO2 thin films were directly deposited on a soda lime glass substrate placed in an aqueous solution containing Ti- and V-fluoro complex ions, followed by annealing. The thin films were analyzed by XRD, XPS, UV-vis. V4+ ions were introduced into the lattice of TiO2 through in-situ substituting Ti4+. The absorption edge of V-doped TiO2 films shifted to visible light region. The highly efficient photocatalytic activity was verified by the decomposition of methylene blue under visible light irradiation.
