Abstract
Titania-coated silica microspheres containing between 0.5 and 3.0 theoretical layers of TiO2 have been prepared by homogeneous precipitation of TiCl3. All these xTiO2-SiO2 materials were characterized by X-ray diffraction, UV-Vis, FT-Raman and XPS. Calcination of silica-supported precipitates leads to the formation of titanium dioxide. TiO2 species are distributed on the surface as small anatase crystals and possess a titania-like behaviour with a much better performance than bulk TiO2 for the photodegradation of phenol. Crystal size of titania particles is critical for optimum performance of the catalyst since it determines the appropriate surface exposure of titanium sites.
