Abstract. Pure titania and titania doped with Zn2+ were prepared by homogeneous hydrolysis in aqueous solution with urea and thioacetamide as precipitating agents. The materials were characterized by XRD, TEM, BET and BJH analysis, which show microporous, nanaocrytsalline anatase phase titania in the size range 4– 5 nm and specific surface area 200–500 m2/g. Adsorption and photocatalyti…
