概要 | In situ surface enhanced Raman has been used to study water molecules adsorbed on a silver electrode in 0.5 M alkali-hydroxide aqueous solutions. Raman spectra and cyclic voltammograms were measured simultaneously while the electrode potential was swept continuously. The alkali-hydroxide solutions were LiOH, NaOH, KOH and CsOH. Raman lines associated with water molecules are identified by a comparison with those obtained for aqueous solutions with D2O instead of H2O. Strong Raman lines, which are associated with the existence of oxygen species adsorbed on silver electrode, were observed in a limited region of electrode potential. The variation of Raman intensities of water molecules, when the electrode potential is scanned, is discussed in terms of the different roles of the cations of the respective alkali-hydroxide solutions. |
