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.
