Abstract

The reduction of nitric oxide by ammonia on platinum catalysts has been investigated in the temperature range 300 to 400°C at reactant partial pressures between 0.05 and 5 mbar. During a combined potentiometric and kinetic study, a discontinuous change in both the reaction rates and the surface state has been observed at a partial pressure ratio for nitric oxide:ammonia of 1.5. If ammonia is in excess in the gas phase then nitric oxide is directly reduced to nitrogen. However, an excess of nitric oxide leads to a strong formation of nitrous oxide, and the nitrogen formation thus proceeds nitrous oxide.
