The selective oxidn. of NH3 into N over Cu, Ag, and Au catalysts at room temp. to 400°C using different NH3:O2 ratios is described. The effect of adding CeOx and Li2O on activity and selectivity is also discussed. Results showed Cu and Ag are very active and selective toward N2; however, multi-component catalysts, M/Li2O/CeOx/Al2O3 (where M = Au, Ag, Cu) performed best. On all 3 metal-contg. catalysts, activity and selectivity was affected by particle size and intera
