Photoactivity of anatase-rutile TiO 2 nanocrystalline mixtures obtained by heat treatment of titanium peroxide gel
Original language description
Nanosized titanium dioxide photocatalysts with anatase structure or mixture of anatase and rutile phases have been synthesized. Homogeneous precipitation of aqueous solutions containing TiOSO 4 and ammonia and following treatment with H 2O 2 was used toprepare porous yellowish (Ti-Per) gel. The gel was lyophilized for 48h and (Ti-Per)LYO-powder was obtained. Single phase anatase TiO 2 samples were prepared by heating of the (Ti-Per)LYO powder. The lamella-like particle morphology of TiO 2 samples determined by SEM were stable in air up to 950°C. The structure evolution during heating of the starting (Ti-Per)LYO powder was studied by DTA and XRD analyses in overall temperature range of phase transformation. The morphology and microstucture characteristics were also obtained by HRTEM and BET methods. The photocatalytic activity of the sample titania TI-LYO/950 heated to 950°C in air contained 78.4% anatase and 21.6% rutile was higher than standard Degussa P25. Titania sample TI-LYO/950
