The role of water vapour in the hydrogenation of nitric oxide at a Zn(0001) surface
Abstract
Nitric oxide is dissociatively chemisorbed at a Zn(0001)surface at 80 K, both the chemisorbed nitrogen and oxygen are stable up to 470K; in the presence of coadsorbed water, hydrogenation of the adsorbed nitrogen occurs at 200K by hydroxyl species formed as a result of the activation of molecularly adsorbed water by chemisorbed oxygen generated in the dissociative chemisorption of NO.
