Title (EN) CERIUM- AND ZIRCONIUM-BASED MIXED OXIDE
(FR) OXYDE MIXTE A BASE DE CERIUM ET DE ZIRCONIUM
Abstract:
(EN) The present invention concerns a mixed oxide of zirconium, cerium, lanthanum and at least one oxide of a rare earth other than cerium and lanthanum that comprises two crystalline phases and that has a large specific surface area. The invention also concerns the method for preparing same and the use thereof in catalysis.
(FR) ABREGE DU CONTENU TECHNIQUE DE L'INVENTION La présente invention est relative à un oxyde mixte de zirconium,de cérium, de lanthaneet d'au moins un oxyde d'une terre rare autre que le cérium et le lanthane qui comprend deux phases cristallines et qui présente une surface spécifique élevée. L'invention est aussi relative à son procédé de préparation et à son utilisation en catalyse.
