“…Due to the increased reactivity and lattice perturbation at defect sites, it is reasonable to think that O sub formation may be enhanced on a surface with a greater number of defects. On Pd(1 0 0), for example, defects were observed to facilitate the formation of O sub from surface-bound oxygen atoms [22]. Pt, however, has proven to be resistant to O sub formation, with small amounts of O sub formed near step edges after repeated high temperature exposures to O 2 [7].…”

“…Oxygen adsorption and desorption on a Pd(100) surface with mesoscopic defects were studied by photoemission electron microscopy (PEEM). On the defect surface, oxygen is adsorbed on the surface and on subsurface sites; while on the perfect Pd(100) surface only surface oxygen is present [8]. On the perfect Pd(100) surface, Nyberg and Uvdal found that oxygen orders in a p(2 × 2) superstructure and the Pd-O stretching frequency has a value of 347 cm −1 [9].…”
