Electrosynthesis of ammonia with high selectivity and high rates via engineering of the solid-electrolyte interphase

“…Currently, the only known reliable method of electrochemical NH 3 synthesis at ambient temperature is lithium-mediated nitrogen reduction (LiNR), which was first reported by Fichter et al in 1930 8 and later studied by Tsuneto et al in the 1990s. 9,10 CONTEXT & SCALE Lithium-mediated nitrogen reduction (LiNR) is a promising pathway to produce ammonia (NH 3 ) in a modular and distributed manner, but the process is still limited by low NH 3 production rate and selectivity.…”

Understanding the Factors Determining the Faradaic Efficiency and Rate of the Lithium Redox-Mediated N2 Reduction to Ammonia

“…The importance of the Li-mediated NRR has been only recently recognized, ,, notwithstanding that the process was first demonstrated as early as in the 1930s by Fichter et al and was also investigated in the 1990s by Tsuneto and co-workers. , The latter studies, along with some of the recent work, ,,, have majorly focused on maximizing the amount of ammonia generated in a constant current mode with little emphasis put on the electrode potentials required to maintain the reported reaction rates, which were trending more negative during the experiments. Uncontrolled potentials complicate the understanding of the kinetics and mechanism of the electrochemical processes involved, including the electrolyte breakdown and formation of various compounds on the electrode surface.…”

“…Conversion of dinitrogen to ammonia mediated by the lithium 0/+ redox couple (Scheme 1) currently remains the only process that has been genuinely proven 1−3 to enable the electrochemical nitrogen reduction reaction (NRR) at yield rates and faradaic efficiencies that are sufficiently high to justify its further research and development into an NH 3 electrosynthesis system of applied significance. 4 The importance of the Li-mediated NRR has been only recently recognized, 1,3,5 notwithstanding that the process was first demonstrated as early as in the 1930s by Fichter et al 6 and was also investigated in the 1990s by Tsuneto and coworkers. 7,8 The latter studies, along with some of the recent work, 3,5,9,10 have majorly focused on maximizing the amount of ammonia generated in a constant current mode with little emphasis put on the electrode potentials required to maintain the reported reaction rates, which were trending more negative during the experiments.…”

Enhancement of lithium-mediated ammonia synthesis by addition of oxygen

“…A similar lithium-mediated method was first published by Fichter et al . in 1930 ( 21 ) and later investigated with a near-aprotic solvent by Tsuneto et al . in the 1990s ( 22 , 23 ).…”
