Abstract

An emission control catalyst includes copper-ceria to boost low temperature CO oxidation performance, generate exothermic heat during the process, and reduce HC and NO x emissions. As a result, system performance is boosted at equal catalyst cost or maintained at a reduced catalyst cost. In one embodiment, an engine exhaust catalyst includes a first washcoat layer having at least one of a platinum-based catalyst, a palladium-based catalyst, and combinations thereof; and a second washcoat layer having copper-ceria.

Claims (4)

1 . An engine exhaust catalyst comprising:

a first washcoat layer having a platinum-based catalyst;

a second washcoat layer; and

a copper ceria catalyst in at least one of the first and second layers.
