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.
