Outline of Final Research Achievements |
Transition metal-typical element compounds have recently been reported to be highly active in hydrogen evolution reactions (HER) and are expected to be an alternative catalyst to precious metal catalysts. We have shown that phosphorus terminated surfaces of Ni2P may have high reactivity by first-principles calculations. In this study, we showed the high HER activity of the phosphorus terminated surface of Ni2P by electrochemical measurements and clarified the mechanism of the HER reactivity by transition metal-typical element compounds.

Academic Significance and Societal Importance of the Research Achievements |
水素生成は、水素社会の基盤となる技術であり重要である。水素生成反応に高い活性を示す触媒はPtが知られているが、高価であることから、代替となる触媒の開発が望まれている。本研究ではNi2Pを電極触媒として用いると高い水素生成反応特性を示すことを実験的に示し、また、その反応機構を実験と理論両面から解明することで、更なる活性向上の指針を示した。
