Abstract

A zoned catalyzed substrate monolith comprises a first zone and a second zone that are arranged axially in series. The first zone comprises a platinum group metal loaded on a support and a first base metal oxide or a first base metal loaded on an inorganic oxide. The first base metal oxide is iron oxide, manganese oxide, copper oxide, zinc oxide, nickel oxide, or mixtures thereof. The first base metal is iron, manganese, copper, zinc, nickel, or mixtures thereof. The second zone comprises copper or iron loaded on a zeolite and a second base metal oxide or a second base metal loaded on an inorganic oxide. The second base metal oxide is iron oxide, manganese oxide, copper oxide, zinc oxide, nickel oxide, or mixtures thereof. The second base metal is iron, manganese, copper, zinc, nickel, or mixtures thereof. The second base metal is different from the first base metal.
