Nitrogen oxide (NOx) and carbon oxide (COx) released from industrial processes and motor vehicle exhausts are strong greenhouse gases.1 They mainly cause a destruction of the ozone layer. Therefore, an abasement of these gases is of importance for long-term reduction of environmental problems. The reaction mechanism of the elimination for COx and NOx is a crucial step for the development of efficient catalysts for this reaction. Several catalysts such as zeolites2-6, graphene7-9 and porphyrins10 are used for reduction of N2O by converting it into the N2 and O2 molecules. Transition metals such as Fe, Co, Ni, Pt and Rh in catalysts showed high activity for N2O decomposition.11-13
