Abstract

Abstract The effect of zirconium dioxide addition on crystal structure of sol–gel TiO 2 mesoporous films and powders has been investigated by means of Raman spectroscopy, X-Ray diffraction, and Atomic force microscopy. Zirconium incorporation (up to 30 mol%) into TiO 2 lattice resulted in the formation of Ti 1 − x Zr x O 2 solid solution with anatase structure for the binary powders has been proved. Appearance of tetragonal ZrO 2 phase was observed for the samples with high zirconium content.
