Abstract

The present invention relates to a catalyst, in particular to a three-way diesel catalyst, for the treatment of a diesel exhaust gas, the catalyst comprising a substrate and two specific coatings disposed thereon, wherein the first coating particularly comprises a first platinum group metal component supported on a first oxidic support material, a second platinum group metal component supported on a second oxidic support material, and a first oxygen storage component, wherein at least 30 weight-% of the first oxygen storage component consist of cerium oxide, calculated as CeOa, and wherein the second coating particularly comprises a third platinum group metal component and a fourth platinum group metal component, wherein the third platinum group metal component and the fourth platinum group metal component are supported on a third oxidic support material. Further, a process for the preparation of such a catalyst is disclosed as well as a use thereof.
