Abstract
The co‐adsorption of molecular nitric oxide and hydrogen on Ru(001) has been studied using electron energy loss spectroscopy. Previous work has shown that molecuar nitric oxide occupies sites of single and multiple (probably threefold) coordination. Competitive adsorption between hydrogen and the latter form of molecular NO is interpreted in terms of hydrogen preferentially adsorbing into threefold symmetric sites. This is consistent with experimental results and theoretical calculations for other surfaces.Keywords
