CA 2716620
The composition of the invention comprises at least one supported oxide chosen from zirconium oxide, titanium oxide or a mixed zirconium titanium oxide on an alumina-based or aluminium-oxyhydroxide-based support and is characterized in that, after calcination for 4 hours at 900°C, the supported oxide is in the form of particles deposited on said support, the size of said particles being at most 10 nm when the supported oxide is zirconium oxide and being at most 15 nm when the supported oxide is titanium oxide or a mixed zirconium titanium oxide. The composition of the invention may be used as catalyst, especially for the selective reduction of NOx.
La composition de l'invention comprend au moins un oxyde supporté choisi parmi l'oxyde de zirconium, l'oxyde de titane ou un oxyde mixte de zirconium et de titane sur un support à base d'alumine ou d'oxyhydroxyde d'aluminium, et elle est caractérisée en ce que, après calcination 4 heures à 900°C, l'oxyde supporté est sous forme de particules, déposées sur ledit support, dont la taille est d'au plus 10 nm lorsque l'oxyde supporté est l'oxyde de zirconium; d'au plus 15 nm lorsque l'oxyde supporté est l'oxyde de titane ou un oxyde mixte de zirconium et de titane. La composition de l'invention peut être utilisée comme catalyseur, notamment pour la réduction sélective des NOx.
