Specimens of titania with platinum in various oxidation states deposited by a photocatalytic method, as well as mixture of PtO₂ + TiO₂, and PtO₂ have been studied by means of XPS, TEM and UV-VIS diffuse reflectance spectroscopy. Activities of the specimens in thermal and photocatalytic complete oxidation of gaseous acetone and CO by atmospheric oxygen at 40°C have been evaluated using a flow-circulating reactor. Photocatalytic activity increases with lowering of Pt oxidation state. Possible reasons of this behavior are discussed.
