SYNTHESIS OF TiO2 NANOPOWDER BY THERMAL DECOMPOSITION OF TITANIUM PEROXO COMPLEX IN THE PRESENCE OF NaCl AS A TEMPLATE

Dispersed titanium dioxide was synthesized by thermal decomposition (700°C) of titanium peroxo complex in the presence of sodium chloride as a template at different precursor/template ratios. Its comparative analysis was carried out with titanium dioxide obtained in the absence of a template. Titanium dioxide is represented by two crystalline phases - anatase and rutile. It has been established that the presence of sodium chloride during the synthesis of nanodispersed TiO2 leads to the formation of an aggregate of spherical TiO2 crystallites with an average diameter of 19 nm. The dominant crystalline phase is anatase (>90%). With an increase in the NaCl content in the initial mixture, an increase in the proportion of the
