Abstract

The oxidation states of Pt(111), Pt(100) and Pt(110) in 0.1 M HF solution were analyzed as a function of the electrode potential by EC-XPS. We have, for the first time, clarified the structural effects on the surface oxidation processes at Pt electrodes on the basis of the coverages of each type of oxygen species.
