Crystal platinum metals, underpotential deposition

Underpotential deposition (UPD) of foreign metal adatoms on platinum single crystals in different acid electrolytes occupies a special position in interfacial electrochemistry. Of various systems examined the underpotential deposition of Cu on a Pt(lll) surface has been of particular interest since the interpretation of the nature of the Pt(lll)-Cu-Anion structure have been the subject of considerable controversy. Overviews with some different perspectives can be find in the References. [J-I3].
