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.

Micro- and nanostructured titanium(IV) oxide in sono-, photo- and sonophotocatalytic degradation of xanthene dye rhodamine b (Review)

Adsorption methods for removing Rhodamine B from wastewater and oxidative degradation methods based on the use of advanced oxidation processes (sonolysis, photolysis, sono-, photo- and sonophotocatalysis) are considered. It has been established that naturally occurring materials (such as clays, zeolites, coal ash, anaerobic sludge, agricultural solid wastes) and their modified or activated analogues are used as adsorbents for the removal of Rhodamine B.

Structural Investigations of Titanium(IV) Oxide Powder Doped with Sulphur

Structural features of titanium(IV) oxide powder doped with sulphur (S-TiO2) have been determined. Using scanned electronic microscopy, X-ray phase and diffraction analyses the oxide morphology has been studied. Surface composition of S-TiO2 nanoparticles has been examined by X-ray photoelectron and IR-spectroscopy.
