Abstract

Catalyst material comprising a ternary spinel mixed oxide for treatment of an exhaust gas stream via direct decomposition removal of NOx to Nand O. The low temperature (from about 400° C. to about 650° C.), direct decomposition is accomplished without the need of a reductant molecule. In one example, Mn may be incorporated into metal oxide, such as CuCoOspinel oxide, synthesized using co-precipitation techniques.
