“…The sol-gel method of titanium dioxide obtaining combines the processes of chemical conversion of titanium salts or organotitanium substances solutions into monomeric titanium hydroxide Ti(OH)4 and its subsequent polycondensation with the formation of colloidal particles [10][11][12][13][14][15][16][17]. In comparison with other methods, sol-gel technologies make it possible to influence the structure and morphology of TiO2 particles, optimize energy costs, as well as use simple and affordable technological equipment [4].…”

TiO2-based nanomaterials are attracting much attention in many areas, such as photocatalysis, photoelectricity, probing, electrochromism, photochromism, etc. They are widely used in paints, polymers, sunscreens, and toothpaste. There are various ways of synthesis that affect the size, shape, and crystallinity of TiO2 nanoparticles. The main methods of obtaining titanium dioxide (with the structure of anatase, rutile or brookite) in the form of spheres, rods, fibers, and tubes include: sol-gel technology, hydrothermal and solvothermal methods, microwave method involving high-frequency electromagnetic waves, template method, electrodeposition, a sonochemical method using ultrasound, chemical and physical vapor deposition, "green" methods, etc. This literature review presents modern scientific results on the production of TiO2 nanoparticles by various methods.

“…The authors of work [12] used a sol-gel method in order to synthesize samples of nanosized titanium dioxide at different pH (pH = 3; 7; 8; 9 and 10). Titanium tetrabutoxide Ti(C4H9O)4, ethanol (95%), and distilled water in a volume ratio of 1:1:4 were used as precursors.…”

The titanium oxide (Ti 3 O 5 ) microcrystals were synthesized by using solid-phase sintering from a mixture of titanium Ti and titanium dioxide TiO 2 powders. Subsequently, Ti 3 O 5 nanocrystals were produced by using high-energy ball milling for 15 -480 minutes. A full-profile analysis of the X-ray diffraction spectra of milled Ti 3 O 5 powders showed that high-energy milling does not lead to disordering or changing of the structure and stoichiometry, the structure remains monoclinic (sp. gr. C2/m), and XRD reflections are broadened due to the small particle size and microdeformations. Experimental data show that increasing of the milling time leads to decreasing of the coherent scattering regions up to 26 nm, increasing of the powder volume fraction of the nanophase up to 81 %, and increasing of microdeformations value. The morphology and the surface area of milled nanopowders were examined by SEM, HRTEM and BET techniques. KEYWORDS high-energy ball milling, Ti 3 O 5 , XRD, BET, SEM, HRTEM ACKNOWLEDGEMENTS The work was carried out in accordance with the state assignment for the Institute of Solid State Chemistry of the Ural Branch of the Russian Academy of Science (No.
