Synthesis and stabilization of nano-sized titanium dioxide

The published data on the preparation and the dispersion-structural properties of nano-sized TiO₂ are considered. Attention is focused on its sol–gel synthesis from different precursors. The possibilities for the purposeful control and stabilization of properties of TiO₂ nanopowders and sols are analyzed. Information on physicochemical methods used in studies of the particle size and the phase composition of nanodisperse TiO₂ is presented. The prospects of using nano-sized TiO₂ in medicine and nanobiotechnology are considered.
