Outline of Final Research Achievements

Surface-enhanced infrared absorption spectroscopy (SEIRAS), based on an effect in which infrared absorption of molecules adsorbed on metal surfaces, has been demonstrated to be a very powerful tool in studying fundamental phenomena and reactions at the electrochemical interface at a molecular scale. This project aimed at expanding the application of SEIRAS to other solid/solution interfaces, especially to technologically important interfaces. The capability of SEIRAS has been demonstrated through the analyses of electrocatalytic formic acid/formate oxidation in direct fuel cells, the dynamics of solvated cations with electrified surfaces, structures and reactions of lipid bilayers and protein membranes, adsorption of corrosion inhibitors on metal surfaces, and others.
