Abstract

The branching of the intermediate N2O decomposition vs. the desorption was studied in a steady-state NO + CO + O2 reaction on Pd(110). Three surface-nitrogen removal processes, i.e., N2O(a) → N2(g) + O(a), N2O(a) → N2O(g) and 2N(a) → N2(g), are operative. Only about 20% of N 2O(a) was desorbed without decomposition for a (NO:CO = 1:1) mixture. The fraction increased steeply with increasing surface oxygen.
