Preparation, characterization and photocatalytic activity of optically transparent titanium dioxide particles
چکیده انگلیسی

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 HRTEM. The crystallinity of the samples and its photocatalytic 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 II dye under UV radiation, in comparison to Degussa P25 photocatalyst.
