英文摘要Due to the rich chemistry at the step edge, the vicinal surfaces are widely used as model system of realistic catalysts for the mechanism study. To provide insight into the influence of different type of steps on the reactivity, density functional theory (DFT) calculations and X-ray Photoelectron Spectroscopy (XPS) measurements have been used to study the CO and H adsorption on Rh(553) and Rh(322) surfaces, which have same width of (111) terrace but different type of steps (111) and (100), respectively. We found that CO molecules prefer to adsorb atop sites at the step edge. With increase of the coverage, CO will populate the terrace sites. At low coverage of CO, adding H to the system, CO molecules are moved entirely to the terraces on Rh(553), while stays at the step edge but changes to bridge sites on Rh(322). DFT calculations reveal that the different coadsorption pattern formed is due to the formation of favorable 1D metal hydride along the step edge on Rh(553). The different adsorption parrterns may affect the reactivity between CO and H, the main components of the syn-gas, whose conversion to the liquid fuel is crucial to the energy consumption of society.
