Outline of Final Research Achievements

In a plasma/liquid (P/L) reaction, activated nitrogen abstracts hydrogen from water and the reduction (hydrogenation) of nitrogen proceeds at room temperature, normal pressure and without a catalyst. This is the reaction that I discovered for the first time in the world. Over the past five years, we have been working to elucidate the reaction mechanism. In the P/L reaction, it was demonstrated that ammonia (NH3) and hydrogen (H2) can be synthesized simultaneously using only nitrogen (N2) and water (H2O) as raw materials. The results of these five years of research have elucidated the reaction mechanism and clarified the possibility of improving reaction efficiency (improving energy yield).

Academic Significance and Societal Importance of the Research Achievements

相界面反応(Plasma/Liquid (P/L) reaction)は、窒素と水だけを原料として、常温・常圧・無触媒の1段階反応で水相では選択性100%でのアンモニア合成が進行し、気相ではNOとH2が生成できる。つまり新燃料(新エネルギー)として注目度の高いアンモニアと水素を、窒素と水から常温・常圧・無触媒の経済的プロセスで合成できる新反応である。
本研究の5年間の成果により、反応機構を解明し、加えて反応効率化(エネルギー収率向上)の可能性を明らかにしてきており、本研究(本技術)を実用化すれば、大気と水の元素循環により資源・エネルギー循環を実現する技術となる。
