Abstract

Morphology of clean Ni(111) and MnO_x (x between 0.2 and 0.5)-modified Ni(111) surfaces has been studied by scanning tunneling microscopy (STM) under ultrahigh vacuum conditions. Oxide islands were clearly observed. The nickel-oxide perimeter site concentration was measured as a function of oxide coverage and was found to correlate very well with results from earlier CO thermal desorption studies of the same system. These results strongly suggest the importance of perimeter sites in systems exhibiting strong metal-support interaction.
