Abstract
Catalysts including multi-transition metal doped copper-cobalt spinel mixed oxide catalyst materials for direct NOdecomposition with selectivity to Nfrom combustion engine exhaust, while minimizing formation of the NO product. In one example, the catalyst may include a ternary zinc-doped copper-cobalt spinel material or a quaternary manganese+zinc doped copper-cobalt spinel material. The catalysts are effective for reducing NO to Nat suitable temperatures of 350-500° C., with and without excess Opresence.
