Zusammenfassung:Aircraft catalysts, systems, and methods are disclosed. In one or more embodiments, the catalysts comprise a substrate, at least a first washcoat layer on the substrate comprising a refractory metal oxide support having a catalytic metal component dispersed on the refractory metal oxide support, and an overcoat washcoat layer on the first layer comprising a manganese component. Catalysts prepared in accordance with embodiments of the invention exhibit improved life when used in aircraft.
