Synthesis and Properties of Ni–Cu Alloy Supported on Mg–Al Mixed Oxide Catalyst for Automotive Exhaust

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·1/2MgAl2O4. On the NO–CO reaction evaluation after pretreatment in oxidation atmosphere, the Ni0.3Cu0.2/2MgO·1/2...

Zusammenfassung:	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·1/2MgAl2O4. On the NO–CO reaction evaluation after pretreatment in oxidation atmosphere, the Ni0.3Cu0.2/2MgO·1/2MgAl2O4 showed higher activity than a Cu/Al2O3 catalyst. In the evaluation by using model gas simulated automotive exhaust, the Ni0.3Cu0.2/2MgO·1/2MgAl2O4 catalyst showed high catalytic activity, especially for hydrocarbon oxidation in reducing atmosphere.
