AbstractPolycrystalline tungsten-doped titanium dioxide nanopowders within a dopant concentration of 0-1 at.% were prepared by a one-step flame spray synthesis (FSS). Mixtures of titanium tetra-isopropoxide dissolved in ethanol and tungsten hexacarbonyl solubilized in tetrahydrofuran were used as precursors. The specific surface area (SSA) of the powders was between 40 and 130 m

Doped Titanium Dioxide

Nanocrystalline tungsten oxide doped titanium dioxide (WOx-TiO2) powders were prepared by TiCl4 hydrolysis and characterized by XRD, XPS, UV–Vis absorption spectra and TEM. Results showed that WOx not only hindered the growth of TiO2 particles but also greatly increased the transformation temperature (>800 oC) from anatase to rutile during sintering; the dominant fraction of tungsten oxides was non-stoichiometric tungsten oxide (WxOy) with Wn+ (4<n<6), which could easily substitute Ti4+ in the lattice of TiO2. The light absorption band of TiO2 changed from the near UV to the visible light range (2.68 eV in 1.0 %WOx-TiO2) because of the tungsten impurity energy level induced by WxTi1-xO2. The photocatalysis experiments demonstrated that the MB in aqueous solution was successfully degraded within 1h using WOx-TiO2 with an optimal WOx dosage of 1% under visible light irradiation.
