Abstract

Photoemission-thermal desorption studies for saturation coverage CO on submonolayer Cu-covered Ru(0001), and self-consistent total-energy calculations for CO bound to small-cluster analogs of Cu( 111), Ru(0001), and Cu/Ru(0001) chemisorption geometries are reported. New Cu-perturbed Ru binding sites are observed experimentally with (— 25%) reduced activation energy for desorption and increased molecular photoelectron binding energies ( — 0.3 eV) relative to CO/ Ru(0001). The mixed-metal cluster calculation provides a description of a possible precursor intermediate state for CO desorption, in qualitative accord with experiment.
