The structure and orientation of water molecules at a highly ordered Au(111) electrode surface in perchloric acid have been investigated in-situ as a function of applied potential by means of surface-enhanced infrared absorption spectroscopy. This newly developed infrared spectroscopy technique enables the observation of the electrode/electrolyte interface at a very high sensitivity without interference from the bulk solution. The spectrum of the interfacial water significantly differs from that of bulk water and drastically changes in peak frequencies and band widths around the potential of zero charge (pzc) of the electrode and at about 0.3 V positive from the pzc. The interfacial water molecules are weakly hydrogen-bonded at potentials below the pzc and form a strongly hydrogen-bonded ice-like structure at potentials slightly above the pzc. The ice-like structure is broken at more positive potentials due to the specific adsorption of perchlorate ion, where one OH moiety of water is non-hydrogen-bonded ...

Au (111) electrodes have been emersed from sulphuric acid solutions and their surfaces studied in UHV by LEED, RHEED and AES. It is shown that, after evacuation, sulphuric acid forms an ordered two-dimensional overlayer on Au (111), the structure of which bears some relation to that of crystalline H 2 SO 4 . This H 2 SO 4 overlayer, which is independent of the emersion potential, does not remove the (1 × 23) surface reconstruction of Au (111).
