New Generation Photocatalysts: How Tungsten Influences the Nanostructure and Photocatalytic Activity of TiO(2) in the UV and Visible Regions
Original language description
Tungsten-doped anatase was prepared by a thermal hydrolysis of aqueous solutions of peroxo complexes of titanium and tungsten. The synthesized samples included X-ray diffraction, high-resolution transmission electron microscopy, selected area electron diffraction, Raman spectroscopy, specific surface area, and porosity determination. W doping resulted in a decrease of the unit-cell volume of anatase at lower W contents and an increase at higher W contents. The position of the most intense Raman band ofthe E(g) mode (near 147 cm(-1)) also has a local minimum at medium-doped titania (1.1-3.6% Win titania). W doping increases the temperature of anatase-to-rutile transformation by about 100 degrees C compared with nondoped anatase. The photocatalytic activity of doped titania samples was determined by decomposition of Orange II dye during irradiation at 365 and 400 nm. Specimens with moderate W doping (1.0-3.3% W) perform best: they enhance the corresponding reaction rates 10 times at 365
