Abstract

The present invention relates to a composite of cerium, zirconium and samarium components, a catalyst composition containing such composite and the use of the catalyst composition for the treatment of a gas stream to reduce contaminants contained therein. The catalyst composition has the capability of substantially simultaneously catalyzing the oxidation of hydrocarbons and carbon monoxide and the reduction of nitrogen oxides.
