Outline of Final Research Achievements

Catalysts are indispensable in the production of chemical products, and heterogeneous reactions using solid catalysts are "low environmental load" because continuous production of chemical products and recovery and reuse of catalysts are possible. However, solid catalyst reactions are more stable (inert) and have lower surface energy than homogeneous reactions using molecular catalysts. In this research, we challenged the production of valuable substances (organic amines, amino acids, etc.) from nitrogen (N2) using catalysts with the surface energy of solid materials raised to the limit. If this research can produce valuable materials from N2, it will become a "dream nitrogen circulation technology." Furthermore, it has become a technology that can be manufactured with "low environmental impact" and contributes to the "Sustainable Development Goals (SDGs)" that promote human health and welfare.

Academic Significance and Societal Importance of the Research Achievements

本研究では、固体触媒により『低環境負荷』でN2を活性化して有価物を製造する『新たなN2循環技術を開発』することを目的とする。これまで分子触媒については、N2活性化の報告例は多いが、いずれも『NH3合成』を目的としている[Eur. J. Inorg. Chem., 1337, 2018.等]。一方、固体触媒については、Feや担持Ru触媒によるN2からのNH3合成の研究報告例がある[Nat. Chem. 4, 934, 2012等]。しかし、特殊反応場を活用した『N2活性化』と『有価物合成』の報告例は世界にないため、本研究は独自性・創造性を有する。
