Title (EN) MIXED OXIDE WITH ENHANCED REDOX PROPERTIES
(FR) OXYDE MIXTE À PROPRIÉTÉS REDOX AMÉLIORÉES
Abstract:
(EN) The present invention relates to a mixed oxide based upon cerium, an element which is Al or Si and a base metal (BM). The invention also relates to the process of preparation of said mixed oxide and to the use of said mixed oxide for the preparation of a catalytic converter. The invention also relates to a process for the treatment of an exhaust gas released by the internal combusion engine of a vehicle, using said mixed oxide.
(FR) La présente invention concerne un oxyde mixte à base de cérium, un élément Al ou Si et un métal de base (MB). L'invention concerne également le procédé de préparation dudit oxyde mixte et l'utilisation dudit oxyde mixte pour la préparation d'un convertisseur catalytique. L'invention concerne également un procédé de traitement d'un gaz d'échappement libéré par le moteur à combustion interne d'un véhicule utilisant ledit oxyde mixte.
