Synthesis and stabilization of nano-sized titanium dioxide

Abstract

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.
