Abstract Electrochemical reduction of nitrate to ammonia (NO 3 RR) holds a great promise for attaining both NH electrosynthesis and wastewater purification. Herein, single‐atom Bi alloyed Pd metallene (Bi 1 Pd) is reported as highly effective NO RR catalyst, showing near 100% ‐Faradaic efficiency with the corresponding yield 33.8 mg h −1 cm −2 at −0.6 V versus RHE, surpassing those almost all ever catalysts. In‐depth theoretical operando spectroscopic investigations unveil that electronically couples its neighboring atoms synergistically activate − destabilize *NO on Pd, leading reduced energy barrier potential‐determining step (*NO→*NOH) enhanced protonation energetics ‐to‐NH pathway.

Electrocatalytic NO reduction reaction to generate NH3 under ambient conditions offers an attractive alternative the energy-extensive Haber–Bosch route; however, challenge still lies in development of cost-effective and high-performance electrocatalysts. Herein, nanoporous VN film is first designed as a highly selective stable electrocatalyst for catalyzing with maximal Faradaic efficiency 85% peak yield rate 1.05 × 10–7 mol·cm–2·s–1 (corresponding 5,140.8 μg·h–1·mgcat.–1) at –0.6 V vs. reversible hydrogen electrode acid medium. Meanwhile, this catalyst maintains excellent activity negligible current density decays over 40 h. Moreover, proof-of-concept Zn–NO battery, it delivers high power 2.0 mW·cm–2 large 0.22 1,077.1 μg·h–1·mgcat.–1), both which are comparable best-reported results. Theoretical analyses confirm that surface favors activation hydrogenation by suppressing evolution. This work highlights electrochemical eco-friendly energy-efficient strategy produce NH3.

Abstract With the development of renewable energy systems, clean hydrogen is burgeoning as an optimal alternative to fossil fuels, in which its application promising retarding global and environmental crisis. The evolution reaction (HER), capable producing high‐purity rapidly electrocatalytic water splitting, has received much attention. Abundant research about HER been done, focusing on advanced electrocatalyst design with high efficiency robust stability. As potential catalysts, metal nanoclusters (MNCs) have studied extensively. They are composed several a hundred atoms, sizes being comparable Fermi wavelength electrons, that is, < 2.0 nm. Different from atoms/nanoparticles, they exhibit unique catalytic properties due their quantum size effect low‐coordination environment. In this review, activity‐enhancing approaches MNCs applied electrocatalysis mainly summarized. Furthermore, recent progress classified different stabilization strategies, freestanding MNCs, organic, carbon supports, introduced. Finally, current challenges deficiencies these for prospected.
