摘要：

N2O activation of Cu-MOR enhanced methanol production at elevated temperatures, to a greater extent than activation by O-2 under optimal conditions. The increase in methanol production by N2O activation was attributed to the facile formation of an active copper center with no formation of inactive intermediate species.
