PALLADIUM OXIDE DISPERSED ON SPINEL OXIDES AS CATALYSTS FOR DIRECT NOx DECOMPOSITION
Active catalysts for the treatment of a low temperature exhaust gas stream are provided containing palladium oxides dispersed on a spinel oxide for the direct, lean removal of nitrogen oxides from the exhaust gas stream. 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, PdO may be dispersed on a surface of a metal oxide support, such as Co.sub.3O.sub.4 spinel oxide, synthesized using wet impregnation techniques. The PdO/Co.sub.3O.sub.4 catalyst system converts nitric oxide to nitrogen gas with high product specificity, avoiding the production of a significant concentration of the undesirable N.sub.2O product.
