| Outline of Final Research Achievements |
The catalytic ammonia formation reaction from nitrogen gas and water was found to proceed very efficiently. This reaction required the use of SmI2 as a reducing agent. We investigated the reduction of SmI3 to SmI2 to obtain SmI2 in 82% yield with 81% Faraday efficiency by using electrochemical reduction method with ionic liquid as electrolytes. The catalytic ammonia production reaction using SmI2 obtained from SmI3 by this method as a reductant was investigated to afford ammonia in up to 48 equiv produced per catalyst.

| Academic Significance and Societal Importance of the Research Achievements |
本研究代表者らが開発に成功したPCP型ピンサー配位子を持つモリブデン錯体を触媒として利用する窒素ガスと水からの触媒的アンモニア生成反応で、化学量論量のSmI2を還元剤として利用する必要があった反応系を、電気化学的還元反応を利用して、実用化に向けて格段に研究を進捗できたことが大きな研究成果である。また、本手法は電気化学的エネルギーを物質エネルギーであるアンモニアへと変換可能であることを示す極めて興味深い研究成果でもある。
