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.
