Abstract
A co-catalyst system for the removal of NOfrom an exhaust gas stream has a layered oxide and a spinel of formula NiCoCoAlO. The system converts to nitric oxide to nitrogen gas with high product specificity. The layered oxide is configured to convert NOin the exhaust gas stream to an NO intermediate, and the spinel is configured to convert the NO intermediate to N.
