Abstract (en)
[origin: WO2017134065A1] The Invention relates to a nitrogen oxide storage catalyst composed of at least two catalytically active washcoat layers on a support body, wherein a lower washcoat layer A comprises cerium oxide, an alkaline earth metal compound and/or an alkali compound, platinum and palladium, and manganese oxide, and an upper washcoat layer B disposed on the washcoat layer A comprises cerium oxide, platinum and palladium and does not contain any alkali and alkaline-earth compounds, and to a method for converting NOx in exhaust gases from motor vehicles which are operated with lean-burn engines.
