Electrochemical oxidation causes the lifting of Pt atoms of the surface layer, substantiating a {ital place}-{ital exchange} mechanism. Furthermore, for a charge transfer of {approx_lt}1.7{ital e}{sup {minus}}/Pt atom, the flat surface is recovered by reduction, while the surface is irreversibly roughened by more excessive oxidation. Roughening involves only the atoms in the top layer.
