Abstract: A nitrous oxide (N2O) removal catalyst composite is described, which includes: a N2O removal catalytic material on a carrier, wherein the catalytic material comprises a platinum group metal (PGM) component on a ceria-containing support having a single phase, cubic fluorite crystal structure. The catalytic material is effective to decompose nitrous oxide (N2O) to nitrogen (N2) and oxygen (O2) and/or to reduce N2O to N2 and water (H2O) and/or (CO2) under conditions of an exhaust stream of an internal combustion engine operating under conditions that are stoichiometric or lean with periodic rich transient excursions. Methods of making and using the same are also provided.

Abstract: Catalytic materials for exhaust gas purifying catalyst composites comprise platinum group metal (PGM)-containing catalysts whose PGM component(s) are provided as nanoparticles and are affixed to a refractory metal oxide, which may be provided as a precursor. Upon calcination of the catalysts, the PGM is thermally affixed to and well-dispersed throughout the support. Excellent conversion of hydrocarbons and nitrogen oxides can advantageously be achieved using such catalysts.

Abstract: A catalyst material for the oxidation of NO comprising a catalyst carrier including a ceria-alumina support having platinum and optionally palladium dispersed on the support is described. When palladium is present, the ratio of platinum to palladium by weight is at least 1:1. The amount of ceria in the support is in the range of 1% to 12% by weight. The catalyst material is useful for methods and systems of abating pollutants from automotive exhaust gas from lean burn engines.
