Abstract:
Provided are catalyst articles, methods of manufacturing catalyst articles, and methods for controlling emissions in diesel engine exhaust streams with catalyst articles, where the emission treatment system of various embodiments effectively treats diesel engine exhaust with a catalyst article. In one or more embodiments, the catalyst articles have a platinum group metal end coating covering an outlet end surface of the catalytic article. In one or more embodiments, a method is provided where an applicator transfers a platinum group metal coating to an outlet end face of a catalytic article.
