Abstract Ammonia (NH 3 ) synthesis via the nitrate reduction reaction (NO RR) offers a competitive strategy for nitrogen cycling and carbon neutrality; however, this is hindered by poor NO RR performance under high current density. Herein, it shown that boron‐doped Ti C 2 T x MXene nanosheets can highly efficiently catalyze conversion of RR‐to‐NH at ambient conditions, showing maximal NH Faradic efficiency 91% with peak yield rate 26.2 mgh −1 mg cat. , robust durability over ten consecutive cycles, all them are comparable to best‐reported results exceed those pristine MXene. More importantly, when tested in flow cell, designed catalyst delivers density ‒1000 mA cm −2 low potential ‒1.18 V versus reversible hydrogen electrode maintains selectivity wide range. Besides, Zn–nitrate battery as cathode assembled, which achieves power 5.24 mW 1.15 . Theoretical simulations further demonstrate boron dopants optimize adsorption activation intermediates, reduce potential‐determining step barrier, thus leading an enhanced selectivity.

Lithium-mediated ammonia synthesis (LiMAS) is an emerging electrochemical method for NH3 production, featuring a meticulous three-step process involving Li+ electrodeposition, Li nitridation, and Li3N protolysis. The essence lies in the electrodeposition of Li+, critical phase demanding current oscillations to fortify solid-electrolyte interface (SEI) ensure voltage stability. This distinctive operational cadence orchestrates nitridation protolysis, profoundly influencing selectivity. Increasing N2 pressure enhances faradaic efficiency (FE) up 20 bar, beyond which proton availability controls selectivity between donor, typically alcohols, key factor, with 1-butanol observed yield highest FE. Counterion salt also be significant, larger anions (e.g., exemplified by BF4–) improving SEI stability, directly impacting LiMAS efficacy. Notably, we report peak FE ∼70% density ∼−100 mA/cm2 via delicate balance conditions, encompassing pressure, salt, their respective concentrations. In contrast recent literature, find that theoretical maximum energy hinges significantly on source, utilizing H2O calculated have achievable 27.8%. Despite inherent challenges, technoeconomic analysis suggests high-pressure more feasible than both ambient modified green Haber–Bosch process. Our finds that, at 100 6 V cell voltage, delivers all-inclusive cost $456 per ton, lower conventional barriers. economic underscores as potentially transformative technology may revolutionize large-scale paving way sustainable future.
