REACTION OF CO WITH NO IN THE PRESENCE OF AN AL2O3 CATALYST CONTAINING COPPER IONS

The CO-NO reaction over catalysis containing copper has been studied b y spectroscopy. Under the reaction conditions both atoms and ions (Cu, Cu2+) are present on the surface. Copper ions take part in the forma tion of isocyanate complex; Cu+ ions, in the formation of carbonyl. NO is adsorbed on oxygen ions to form nitrite. The proportion of various centers depends on reaction conditions. The more reduced catalyst fav ors reaction via an isocyanate complex to form nitrogen. The less redu ced catalyst favors N2O formation.
