ABSTRACT:
A monolithic or honeycomb-catalyst, in particular for purifying the exhaust gases of internal-combustion engines, composed of an inert ceramic or metallic support traversed by parallel flow channels, a layer disposed thereon and composed of catalysis-promoting metal oxide and a catalytically active component supported by the metal oxide, wherein the concentration of the catalysis-promoting metal oxide increases from the periphery to the central axis of the support. Alternatively, the catalysis-promoting metal oxide is essentially equally distributed between central axis and periphery of the support, but concentration of catalytically active component increases from the central axis to the periphery of the support.
