英文摘要 | smox modified rh(l 0 0) surfaces have been in-situ prepared by depositing metallic sin and subsequently oxidizing under controlled conditions, and the interaction between the lanthanide oxide and transition metal has been characterized by means of x-ray photoelectron spectroscopy (xps) and high-resolution electron-energy-loss spectroscopy (hreels) as well as thermal desorption spectroscopy (tds). as evidenced, the adsorption of co on the modified surfaces shows some different features to the original surface of rh(l 00). the covering of smox blocks some sites on the surface and consequently suppresses adsorption of the typical co species with an uptake at about 500 k, while a novel desorption peak centered at 260 k emerges in the co tds. correspondingly, the xp spectrum exhibits a new c is peak at 287.9 ev and 0 is peak at 532.6 ev. the intensity of the low temperature peak varies with the coverage of smox, which shows an actual correlation to the perimeter sites of smox particles on the surface.
