Abstract
Films of doped and un-doped TiO2with transition metals such as tungsten, vanadium and molybdenum were prepared and coated on glass substrates by a simple sol-gel dip-coating method. The doped and co-doped TiO2 samples were characterized by scanning electron microscopy, X-ray diffraction and UV-VIS spectroscopy. The influences of the doping on the size, morphology and optical properties of TiO2thin-films were investigated. The different behavior of doped and undopedTiO2for their photocatalytic degradation of methyl violetand biomethanated spent wash was evaluated.Mo,Wco-doped TiO2and un-doped TiO2 thin-films showed the highest efficiency for sunlight photocatalytic degradation of methyl violet and biomethanated spent wash, respectively. Keywords - TiO2; Thin film; photocatalyst;methyl violet; biomethanated spent wash
