A new Cu-based catalyst for automotive three way catalysts has been investigated. We succeeded in the synthesis of the Ni-Cu alloy supported on Mg-Al mixed oxide catalyst, Ni0.3Cu0.2/2MgO • ½ MgAl2O4. On the NOCO reaction evaluation after pretreatment in oxidation atmosphere, the Ni0.3Cu0.2/2MgO • ½ MgAl2O4 showed higher activity than a Cu/Al2O3 catalyst. In the evaluation by using model gas simulated automotive exhaust, the Ni0.3Cu0.2/2MgO • ½MgAl2O4 catalyst showed high catalytic activity, especially for hydrocarbon oxidation in reducing atmosphere..
