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。如果要克服这种情况,我们将在这项研究中开发一种近红外光谱-电化学技术。它被应用到了我的金属电极中,我们已经成功地观察到了与电离子相关的水分子。所发现的结果是一致的,那些先前在中IR地区发现的,而原位红外反射吸收光谱仪也被应用于类似液体汞和图形的电子。而渗透和/或碳离子的吸收被观察为电潜能的一个功能。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被研究为cyclic voltammManagement and in situ infrared spectroscopy。一个数量的类似红袜的波浪似乎附着在CVs上的小分子,它们在复杂的标记D中发生了变化。在烷基链长度上倾斜,并在晶体学方向上倾斜。特征性电压显微镜也被观察到一个高度定向的焦状图形(HOPG)的电极,以及被吸收的微生物的分子方向是由红外光谱仪确定的。
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.
