Ammonia formation by reduction of nitrogen monoxide with carbon monoxide using copper-deposited ceria in the presence of water

Nitrogen monoxide (NO) conversion to ammonia (NH3) over copper (Cu) catalysts was studied. Above 150 degrees C, Cu/CeO2 demonstrated high NH3 selectivity for the NO-CO-H2O reaction, whereas NH3 formation in the NO-H-2 reaction was negligible at this temperature. For the NO conversion to NH3, the enhancement of water-gas shift reaction was proposed to be effective.
