Abstract: Described is a process for the preparation of a catalyst comprising the steps of: (i) providing one or more support materials; (ii) providing one or more polymers on the support material; and (iii) providing one or more metals on the one or more supported polymers; wherein in step (ii) the one or more polymers do not comprise cross-linked polymers and/or polymers which have been reacted with a cross-linking agent. Also described is a catalyst obtained or obtainable according to said process, as well as the use of the catalyst, in particular in a method for the treatment of automobile engine exhaust gas.

Abstract: Provided is a catalyst composition, in particular a diesel oxidation catalyst, for the treatment of exhaust gas emissions, such as the oxidation of unburned hydrocarbons (HC), and carbon monoxide (CO). More particularly, the present invention is directed to a catalyst structure comprising at least two, specifically three distinct layers, at least one of which contains an oxygen storage component (OSC) that is present in a layer separate from the majority of the platinum group metal (PGM) components, such as palladium and platinum.
