Abstracts

EN

The CO/Pt/Ru(0001) interface has been re-examined, in great detail, by photoelectron spectroscopy of high resolution under UHV conditions. The Ru(0001) substrate has been modified by platinum at coverages less than corresponding to the one, saturated, Pt overlayer, with no Pt/Ru intermixing. The analysis of the extent to which different regions of the photoelectron spectrum allow a detailed characterization of the interface is presented. The CO adsorption displays interaction with two separate phases: the Pt(111) face and the Ru(0001) surface.
