Resumo
The data on phase and chemical transformations of nanosized zirconium dioxide upon annealing at 25–1300°С are presented. The in situ interaction of titanium tetrachloride with nanosized zirconia annealed at 200–800°С has been studied. The revealed regularities of the change of titanium content and the Cl/Ti ratio in the chemisorbed groups have confirmed that TiCl4 predominantly reacts with zirconia treated at up to 400°С via the hydroxyl groups to yield the TiCl4–n fragments. In the case of zirconia treated at higher temperature, the interaction with TiCl4 involves the coordination-unsaturated Zr+ and Zr–O– centers as well.
