Outline of Final Research Achievements

The purpose of this research is to develop a new electrochemical organic hydride method by a one-pot reaction using Au electrode modifying self-assembled monolayer(=SAM) as hydrogen storage material. In this study, benzenethiol or phenylethanethiol as a hydrogen storage material was modified on Au electrode. By optimization of the modification conditions, 3.4×10＾14 molecules per unit area of the material was adsorbed on the electrode. And the redox peaks of the SAM were confirmed by cyclic voltammetry.

Academic Significance and Societal Importance of the Research Achievements

本研究は、電気化学的手法による有機ハイドライド法で課題であった、水溶性の低い水素貯蔵材料に効率の良い水素供給方法や、拡散律速により徐々に反応効率の低下を解決するため、自己組織化単分子膜として水素貯蔵材料を電極上に修飾する方法を開発する。本手法によりワンポットでの反応が可能になり、拡散律速の影響が小さいことから新たな水素貯蔵技術として期待できる。
