摘要：

The selective removal of Co3O4 from a cobalt-loaded alumina catalyst resulted in increased activity for the title reaction. indicating that Co3O4 inhibited the reaction but that the residual CoAl2O4-like species acted as catalytically active species. CoAl2O4-like species were sufficiently active for the oxidation of NO to NO2 but much less active for the oxidation of ethene (a side reaction).
