Abstract

Analysis of the structure and phase change of nanodispersed titanium dioxide (obtained using sol-gel method) intercalated with zirconium and niobium (based on the following precursors: zirconium butoxide Zr(OC(CH₃)₃)₄ and niobium ethoxide Nb(OCH₂CH₃)₅) has been performed. X-ray analysis revealed anatase and brookite phases for ТіО₂<Zr> and their transformation into rutile upon annealing at a temperature of 1120 K. It is shown that intercalation of niobium in ТіО₂ stabilizes anatase phase (without transformation into rutile).
