Microwave selective effect: a new approach towards oxygen inhibition removal for highly-effective NO decomposition by microwave catalysis over BaMn(x)Mg(1-x)O3 mixed oxides at low temperature under excess oxygen.

A significant microwave selective effect on oxygen inhibition removal was found for NO decomposition through microwave catalysis over BaMn(x)Mg(1-x)O3 catalysts. Especially, the NO conversion and N2 selectivity were up to 99.8% and 99.9%, respectively for the BaMn(0.9)Mg(0.1)O3 catalyst even with the coexistence of 10% oxygen and low temperature of 250 °C.
