Abstract: Active catalysts for the treatment of a low temperature exhaust gas stream are provided containing copper oxides dispersed on a spinel oxide for the direct, lean removal of nitrogen oxides from the exhaust gas stream. The low temperature, direct decomposition is accomplished without the need of a reductant molecule. In one example, CuOx may be dispersed as a monolayer on a metal oxide support, such as Co3O4 spinel oxide, synthesized using an incipient wetness impregnation technique. The CuOx/Co3O4 catalyst system converts nitric oxide to nitrogen gas with high product specificity, avoiding the production of a significant concentration of the undesirable N2O product.
