Abstract
X-ray photoelectron spectroscopy (XPS) was used to study the electrochemica lly generated oxygen species on a gold surface which was evaporated on an y ttria stabilized zirconia (YSZ) (100) single crystal solid electrolyte. It was found that electrochemical oxygen Dumping to the gold electrode surface , causes the formation of two oxygen chemisorbed states. Their binding ener gies, ranging between 528.8-529.2 and 530.2-531.2 eV, are affected by the A n surface treatment (Ar+ sputtering) and the existence of preadsorbed OHad radicals.
