Abstract

Employing the technique of low energy electron diffraction (LEED) in combination with density functional theory (DFT) calculations, we determined the atomic geometry of the oxygen-rich Ru(0001) surface, which was recently shown to be extraordinarily active in the conversion of CO towards CO₂. The oxygen-rich Ru(0001) surface consists of areas (some 10 μm wide) covered by a (1×1)O overlayer in coexistence with ultrathin (10-20 angstroms) patches of ruthenium dioxide RuO₂ in (110) orientation. The oxide surface structure is characterized by a bulk-truncated RuO₂(110) surface which is terminated by bridging oxygen rows.
