摘要：

During the investigation of the oxidation of CO on palladium clusters supported on MgO(100) we have found two adsorption states of CO that are signified by largely different lifetimes. By comparing the relative amounts of CO adsorbed on these sites we suggest that the sites can be attributed to CO adsorbed on the facets and the edges of the palladium clusters, respectively.
