Transition-metal carbides with metallic properties have been extensively used as electrocatalysts due to their excellent conductivity and unique electronic structures. Herein, NbC nanoparticles decorated carbon nanofibers (NbC@CNFs) are proposed an efficient robust catalyst for electrochemical synthesis of ammonia from nitrate/nitrite reduction, which achieves a high Faradaic efficiency (FE) 94.4 % large yield 30.9 mg h

Abstract Electrocatalytic nitrate reduction to ammonia (NO 3 RR) in a neutral medium is green and effective strategy for treating pollution meanwhile producing ammonia. However, the insufficient active hydrogen (H * ) on catalyst surface resulting from sluggish Volmer step 2 O → H + OH − ), competitive evolution reaction (HER) caused by coupling severely restrict enhancement of NO RR activity. Herein, hydration‐effect boosted ‐rich facilitating electrosynthesis proposed. The introduction hydration‐effect‐promoting element aluminum into copper‐based forming CuAlO , which adjusts electron density distribution system, significantly promotes generation medium. Moreover, rapid charge transfer at CuO/CuAlO interface facilitates kinetics diffusion. More importantly, Al weakens overly strong adsorption intermediates CuO, thereby accelerating hydrogenation process suppressing HER. Thus, under conditions, reached Faradaic efficiency an yield as high 97.81 ± 1.94% 10.21 0.64 mg h −1 cm −2 −1.0 V versus RHE toward RR.
