    ABSTRACT: Vanadium(IV)-doped titanium dioxide (TiO(2)) photocatalyst powders were prepared by the sol-gel method and characterized by Brunauer-Emmett-Teller-specific surface area, scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and ultraviolet-visible spectroscopy. V-doping in the TiO(2) increases the crystal grain size, which decreases the specific surface areas of powders. This V-doping changes the band gap of TiO(2), leading to extend the absorption to visible light regions (400-800 nm). Photocatalytic degradation of methylene blue (MB) in water was investigated as a function of the vanadium content in TiO(2) and was found to follow pseudo first-order rate kinetics. Appropriate content of V-doping is an effective means to improve the photocatalytic activity of TiO(2) for MB degradation under visible light irradiation.
