Adsorption and Dissociation of Nitric Oxide on the Ru(001) Surface

Abstract
The adsorption of nitric oxide and its dissociation on the Ru(001) surface have been studied through the vibrational energies of the adsorbed layer. The inelastic electron scattering measurements show that two distinct states of molecular NO are adsorbed at 130 K. The dissociation of a bridged NO is complete at 316 K, whereas a linear form remains on the surface until 500 K. This is explained by a difference in activation energies for dissociation of NO and by the blocking of sites by nitrogen and oxygen adatoms.
