Photocatalytic property of TiO2 anchored on porous alumina ceramic support by the alkoxide method

Abstract

TiO2 fine particles were anchored on a porous alumina ceramic support by the alkoxide method under various hydrolysis conditions. The photocatalytic property of the obtained TiO2 precipitates, such as the photo-oxidation of ethanol, has been investigated. The amount, the dispersibility and the morphology of TiO2 precipitates on the ceramic support were closely related to the efficiency of the photo-oxidation of ethanol.
