| abstract |
The present invention relates to catalytic compositions suitable inter alia for the photocatalytic oxidation of CO, which comprise: a support comprising, at least on the surface, titanium oxide; and deposited on the titanium oxide present on the surface of the support, a metal mixture containing: platinum, at least partly in the metallic state; and palladium and / or nickel, at least partly in the metallic state. The invention relates more specifically to the use of these compositions for treating gaseous media comprising CO and organic pollutants, for example the interior air of buildings or manned vehicles. |
