英文摘要
Although in situ infrared spectroscopic studies on the molecular structure of electrode I electrolyte interface have widely been performed in the mid-IR region, an infrared energy loss due to the strong absorption of solvent water molecules largely restricted electrochemical cell arrangements. In order to overcome the situation, we have developed in situ near-infrared spectro-electrochemical techniques this research. It was applied to the gold electrode I aqueous electrolyte interface, and we have successfully observed the water molecules associated to the electrolyte anions. The result was found to be consistent with those previously obtained in mid-IR region.In situ infrared reflection absorption spectroscopy was also applied to electrodes such as liquid mercury and graphite. And the adsorption of perchlorate and/or carbonate anions was observed as a function of the electrode potential. The results are expected to provide fundamental information for further development of electrochemical double-layer theory・Adsorption behavior of alkyl viologens on gold single crystal electrodes was studied by cyclic voltammetry and in situ infrared spectroscopy. A number of spike like redox waves due to adsorbed viologen molecules appeared on their CVs, which changed in a complicated manner d。Pending on the alkyl chain length and on crystallographic orientations. Characteristic voltammograms were also observed on a highly oriented pyrolitic graphite (HOPG) electrode, and the molecular orientation of adsorbed viologens were determined by infrared spectroscopy.
