Abstract
The interaction of NO, N2O, CO, O2, H2 and N2 with a stepped Au(3Â 1Â 0) surface has been studied using X-ray photoelectron spectroscopy (XPS) and temperature programmed desorption (TPD). In the temperature (80-500Â K) and pressure (up to 5Â ÃÂ 10â6Â mbar) range used, no adsorption of O2, H2, CO and N2 was observed. However, NO and N2O adsorb on this stepped surface. Decomposition of NO to N2O was observed at temperatures as low as 80Â K. A possible mechanism for the formation of N2O from NO has been discussed on the basis of our TP-XPS results.
