Coadsorption studies on transition metals. Annual report 1 Jan-31 Dec 83
Surface mass spectroscopy was used to study adsorption and coadsorption of active gases on several transition metals. Electron and ion stimulated desorption were employed in conjunction with thermal desorption spectroscopy. It was found to be possible to correlate specific adsorption states for CO on nickel with release of particular ionic species by electron and ion impact. For coadsorbed H/sub 2/ and CO on nickel, an (NiOH)/sup +1/ species was observed by ion induced desorption which was interpreted as evidence for interaction between adsorbates. Coadsorption of H/sub 2/ and CO on rhodium resulted in appearance of a new high temperature mass 2 thermal desorption state. Electron desorption of (OH)/sup +1/ along with modification of the (O)/sup +1/ energy distribution during coadsorption indicated presence of a strong interaction between adsorbed H/sub 2/ and CO.
