Abstract
These days, environmental pollution problems are relevant, therefore, the problems associated with photocatalysis as a direction for the future development of alternative energy are solved by many world scientists. Titanium dioxide TiO2 is known to be a photocatalytic material with many unique properties. However, its use is limited due to its wide band gap and the high recombination rate of electron pairs. The method of direct plasma dynamic synthesis of dispersed titanium dioxide was proposed. It was established that the synthesized product consisted of two fractions which had different sizes: a coarse fraction with particle sizes from ~10 microns to ~100 microns and a fine one - from ~10 nm to ~1 micron. It was also revealed that fractions mainly consisted of two TiO2 crystalline modifications: anatase and rutile with tetragonal syngony.
