SUPPORTS DE CATALYSEUR EN MOUSSE DE SIC REVETUE DE CERINE ET SYSTEMES CATALYTIQUES CORRESPONDANTS

摘要

A catalyst carrier including a surface layer of oxygen-donating oxide, particularly cerine, is disclosed. A catalytic phase deposited on said carrier generally includes platinum and rhodium, thus forming a catalytic system for exhaust pipes, said catalytic phase being readily recoverable by simple leaching.
