Ammonia synthesis through electrochemical nitrate reduction has emerged as a promising alternative to the conventional Haber–Bosch process. However, use of sluggish oxygen evolution reaction anode leads high energy consumption in reduction. In this study, we directly utilize hydrogen gas synthesize ammonia by pairing oxidation with reaction. A significantly lower cell voltage for was realized on 16 cm2 flow electrolyzer. We achieved an impressive yield rate 16.9 mmol h–1 at 1.2 V voltage. Notably, approach exhibits low power 17 kWh kg–1 NH3. The mechanism study shows hydroxyl ions generated from water splitting cathode cross anion exchange membrane react protons anode. Through rigorous technical and economic analyses, is found be economically viable industrial synthesis.

The electrochemical nitrate reduction reaction (NO3RR) emerges as a promising method for ammonia (NH3) production, which faces the dilemma of inhibiting hydrogen evolution (HER) and promoting active (Hads) supply hydrogenation nitrogen intermediates. Here, core–shell structure engineering strategy is developed Cu2–xS/MoS2, where strong Hads adsorption storage capacity can accelerate As result, an eminent NH3 yield 0.178 mmol h–1 cm–2 Faradaic efficiency 84.5% were achieved. A series tests demonstrate that tuning Cu2–xS/MoS2 interface improve activity conversion NO2–, while avoiding HER effectively retain Hads. density functional theory calculation further demonstrates has *H retention ability to promote NO3RR process. This work offers novel perspective on manipulation generation NO3RR.

Abstract Since formaldehyde oxidation reaction (FOR) can release H 2 , it is attractive to construct a bipolar hydrogen production system consisting of FOR and evolution (HER). Although copper‐based catalysts have attracted much attention due their low cost high activity, the performance enhancement mechanism lacks in‐depth investigation. Here, an amorphous‐crystalline catalyst amorphous nickel hydroxide‐coated copper dendrites on foam (Cu@Ni(OH) /CF) prepared. The modification Ni(OH) resulted in hydrophilic aerophobic states Cu@Ni(OH) /CF surface, facilitating transport liquid‐phase species electrode surface accelerating . Open circuit potential (OCP) density functional theory (DFT) calculations indicate that this core–shell structure facilitates adsorption HCHO OH − In addition, catalytic pathway are investigated through situ FTIR DFT calculations, results showed lowered energy barrier for C─H bond breaking H─H formation.
