Outline of Final Research Achievements

Recently, organic hydride method has been developed for realization of a hydrogen society. We have developed a new electrochemical organic hydride method using an electrode modified with a hydrogen storage material. In this research, aromatic thiol compounds were used as a hydrogen storage material. It was found that self-assembled monolayers of phenyl ethanethiol have high stability because of lower Au-S reductive desorption potential.

Academic Significance and Societal Importance of the Research Achievements

本研究では、すでに水素貯蔵物質として利用されているトルエンやナフタレンを基本骨格とした自己組織化単分子膜（SAM膜）を修飾し、SAM膜の安定性の評価や電解前後の構造変化の予測を行った。現行技術であるトルエンを利用した有機ハイドライド法は、プラント規模で実用化されているが、本技術では電極表面上に水素貯蔵物質を修飾することでワンポット化が可能となり、より装置の簡易化が見込まれる。
