Description	Transparentní roztoky oxidu titaničitého (anatasu či brookitu) byly připraveny hydrolýzou vodných roztoků chloridu titanitého za přítomnosti polyethylenglykolu. Připravené vzorky byly charakterizovány měřením distribuce velikostí částic, elektronovou difrakcí (SAED), morfologie a mikrostruktura byly analyzovány elektronovou mikroskopií (HRTEM). Krystalinita a fotokatalytická aktivita částic vzrůstaly v průběhu zrání vodných roztoků až po dobu 60 dní. Fotokatalytická aktivita byla testována formou degradace azobarviva oranži II působením UV záření a porovnávána s aktivitou standardního fotokatalyzátoru TiO2 P25 (Degussa). (cs) The transparent particles of titanium dioxide (anatase or brookite modification) was prepared by hydrolysis of aqueous solution of titanium(III) chloride in the presence of polyethyleneglycol. The prepared samples were characterized by measurement of particle size distribution and selected area electron diffraction (SAED), morphology and microstructure were obtained by HRTENT. The crystallinity of the samples and its photocatallytic activity increased with the time of ageing in the aqueous solutions up to 60 days. Photocatalytic activity of prepared samples of titanium dioxide was determined by degradation of aqueous solution of Orange IT dye under UV radiation, in comparison to Degussa P25 photocatalyst.
