Abstract: An oxidation catalyst composite, methods, and systems for the treatment of exhaust gas emis-sions from a diesel engine are described. More particularly, described is an oxidation catalyst composite including a first oxidation material comprising a first refractory metal oxide support, a rare earth oxide, and palladium (Pd); a second oxidation material comprising a second refractory metal oxide, and platinum (Pt) and palladium (Pd); and a protective overlayer comprising a third refractory metal oxide, platinum (Pt) and, optionally, palladium (Pd), and a molecular sieve promoted with a metal selected from one or more of Cu, Fe, Co, Ni, Mn, V, and, Ag. The oxid-ation catalyst composite is sulfur tolerant.

Abstract: A diesel oxidation catalyst article is provided, which includes a substrate carrier having a plurality of channels adapted for gas flow and a catalyst composition positioned to contact an exhaust gas passing through each channel. The catalyst composition includes a platinum (Pt) component and a sulfur (S)-containing component impregnated onto a refractory metal oxide support and is effective to abate hydrocarbon and carbon monoxide, as well as oxidize NO to NO2 in the exhaust gas. Methods of making and using the catalyst article are also provided, as well as emission treatment systems comprising the catalyst article.
