CA 2318560

New three-way catalysts for vehicles contain, as an oxygen storage component, mixed oxide MnZr. These components are less expensive than state-of-the-art ceria/zirconia, and generally offer improved capacity even after exposure to high temperatures.

L'invention concerne des nouveaux catalyseurs trifonctionnels pour véhicules, qui contiennent, comme composant de stockage d'oxygène, un oxyde mixte MnZr. Ces composants sont moins chers que les céria/zirconia utilisés jusqu'à maintenant, et ont généralement une capacité supérieure, même après avoir été exposés à des températures élevées.
