Zusammenfassung:	The present invention relates to a metal oxide coated composite comprising a core consisting of a mixture of a La stabilised AI2O3 phase and an Ce/Zr/RE2O3 mixed oxide phase, the core having a specific crystallinity, specific pore volume and a specific pore size distribution, and a method for the production of the metal oxide coated composite. La présente invention concerne un composite revêtu d'oxydes métalliques comprenant un cur constitué d'un mélange d'une phase d'Al2O3 stabilisée par un La et d'une phase d'oxydes mélangés de Ce/Zr/Re2O3, le cur ayant une cristallinité spécifique, un volume des pores spécifique et une distribution de la taille des pores spécifique, et un procédé pour la production du composite revêtu d'oxydes métalliques.
