The present invention relates to a lean NOx trap diesel oxidation catalyst for the process, such as trapping and the reduction of unburned hydrocarbons (HC) and carbon monoxide (CO) oxidation and nitrogen oxide (NOx) in the exhaust gas emissions. Catalyst complexes may comprise a catalyst material on a support, the catalytic material is located on the carrier, and the 1 NOx trap layer containing a NOx adsorbent and at least one precious metal component, and positioned on the first 1 NOx trap layer, and NOx adsorbent, at least one noble metal component, and containing a zeolite, for example, comprises a beta zeolite and comprises a NOx trap layer of claim 2 having a hydrocarbon trapping function, in which the zeolite has no backbone substantially free of aluminum. This zeolite is characterized by rather substantially free of framework aluminum in order to minimize the surface acidity and / or a high degree of crystallinity.
