Characterization and Properties of Titanium(IV) Oxide, Synthesized by Different Routes
The article considers the influence of precursor type and sol-gel synthesis conditions of TiO2 on its properties. The obtained TiO2 samples were characterized by X-ray diffraction methods, electron microscopy, as a result of which it was found that all the obtained TiO2 powders have the crystallite size in a nanorange of 2.5–17 nm. It was shown that sorption-photocatalytic properties of TiO2 significantly depend on a phase composition, surface acidity, specific surface area and porosity.
