Abstract: Provided herein is a catalytic article including a catalytic coating disposed on a substrate, wherein the catalytic coating comprises a bottom coating on the substrate and a top coating layer on the bottom coating layer, one such coating layer containing a platinum group metal on a refractory metal oxide support and the other such coating layer containing a ceria-containing molecular sieve. Such catalytic articles are effective toward treating exhaust gas streams of internal combustion engines and exhibit outstanding resistance to sulfur.

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 oxida-tion catalyst composite is sulfur tolerant.

Abstract: An oxidation catalyst composite, methods, and systems for the treatment of exhaust gas emissions from a diesel engine are described. More particularly, described is an oxidation catalyst composite including a first oxidation component comprising a first refractory metal oxide support, palladium (Pd) and platinum (Pt); a NOx storage component comprising one or more of alumina, silica, titania, ceria, or manganese; and a second oxidation component comprising a second refractory metal oxide, a zeolite, and Pt. The oxidation catalyst composite is sulfur tolerant, adsorbs NOx and thermally releases the stored NOx at temperature less than 350°C.
