Abstract
A nitrogen oxide storage catalyst is provided, which has two catalytically active coatings on a support body. The lower coating applied directly to the support body has a nitrogen oxide storage function and includes platinum as a catalytically active component applied to a homogeneous magnesium-aluminum mixed oxide in combination with a nitrogen oxide storage material, in which a nitrogen oxide storage component is likewise present and applied to a homogeneous magnesium-aluminum mixed oxide. The second layer is notable for three-way catalytic activity, and includes palladium applied to aluminum oxide and barium oxide or strontium oxide, but no platinum.
