The techniques of X-ray and u. v. -photoelectron spectroscopy have been used to investigate the chemisorption of the individual molecules nitric oxide, oxygen, and water, and also of coadsorbed nitric oxide and water, at Zn(0001) surfaces. The coadsorbed water-nitric oxide adlayer was reactive below 200 K. Surface hydroxyls were formed through the activation of molecularly adsorbed water by chemisorbed oxygen generated in the dissociative chemisorption of nitric oxide. A detailed mechanism, with each surface species spectroscopically identified, is proposed for the hydrogenation of nitric oxide.
