Characterization and Properties of Titanium(IV) Oxide, Synthesized by Different Routes

The article considers the influence of precursor type and sol-gel synthesis conditions TiO2 on its properties. obtained samples were characterized by X-ray diffraction methods, electron microscopy, as a result which it was found that all powders have crystallite size in nanorange 2.5–17 nm. It shown sorption-photocatalytic properties significantly depend phase composition, surface acidity, specific area porosity. amorphous has improved adsorption properties, while crystalline is enhanced photocatalytic Determined acidic nature explains better sorption photocatalysis relative to cationic dye.
