Abstract
The molecular adsorption of CO was studied on the Ru(1120) surface using lo w energy electron diffraction, high resolution electron energy loss spectro scopy and thermal desorption spectroscopy at room temperature. Two ordered CO phases were observed, a p(1 x 2) phase formed at theta (CO) = 0.25 and a (I x 2)p2mg phase formed at theta (CO) = 0.5 (saturation). In both phases, the CO molecules occupy the on-top sites. Two structural models are sugges ted. (C) 2001 Elsevier Science B.V. All rights reserved.
