Outline of Final Research Achievements

We investigated hydrogen evolution reaction (HER) on high hydrogen overpotential metal electrodes catalyzed by adsorption of some organic molecules. The mechanisms of HER acceleration by adsorption of organic molecules were investigated by surface-enhanced infrared absorption spectroscopy (SEIRAS) and DFT calculation at a molecular level. Electro-hydrogenation or oxidation of the adsorbed organic molecules and catalytic reaction of adsorbed enzyme were also investigated. As mentioned, infrared and DFT calculation clarified the structural and orientation change of adsorbed organic molecules on metal electrodes induced by applied potential at a molecular level.
