The Decomposition of N2O on Ni(110)

Abstract

The catalytic decomposition of N2O to yield N2 gas and adsorbed oxygen has been studied on the Ni(110) surface over the temperature range from 323 to 873K. The combination of Auger electron spectroscopy and molecular beam mass spectrometry has been used to determine the overall rates of production of adsorbed oxygen and N2 gas, and the scattering behavior of unreacted N2O. These data have been analysed to determine the single collision reaction probability as a function of surface temperature and adsorbed oxygen coverage. The reaction precedes from a zero-coverage reaction probability of from 0.97 and 0.52 depending on temperature, to zero reaction probability at an adsorbed oxygen coverage of 1/3 ML. The behavior at partial oxygen coverage is strongly influenced by the presence of a molecular precursor species, especially at low temperatures.
