The two states of methoxy at Cu(110) surfaces identified
Abstract
The coadsorption of methanol rich, dioxygen–methanol mixtures at Cu(110) surfaces is shown to result in an adlayer consisting entirely of a single state of chemisorbed methoxy species; this confirms that a second more strongly adsorbed state of methoxy, observed in the presence of preadsorbed oxygen, is stabilised by the chemisorbed oxygen.
