Zusammenfassung:
The Au(110)-(1 × 2) surface was found to be unaffected in 0.01M HClO4 up to about +0.9 V versus SCE, i.e. the reconstructed surface is stable over the entire double-layer charging region. Oxide formation which starts at +0.95 V versus SCE causes the -superstructure spots in the LEED pattern to gradually disappear, until at an oxygen coverage of about 0.5 monolayers only the fundamental LEED spots are visible. The calcium-induced (1 × 3) reconstruction, on the other hand, was lifted even by the mere contact with the electrolyte, which dissolved the calcium, and was transformed into a (1 × 2) structure.
