Abstract

Three removal processes of surface nitrogen, i.e., (i) the decomposition of the intermediate N₂O(a), (ii) its desorption without decomposition and (iii) the associative desorption of nitrogen atoms, were separately studied in a steady-state NO+CO reaction on Pd(110) through analysis of the angular and velocity distributions of desorbing products N₂ and N₂O. At temperatures below approximately 600 K, the processes (i) and (ii) prevailed, whereas at higher temperatures, the process (iii) contributed significantly. The branching was also sensitive to the CO/NO pressure ratio.
