Abstract Ruthenium (Ru) loaded catalysts show high activity and selectivity for ammonia (NH 3 ) synthesis via electrochemical reduction of nitrate (NO − ), but their practical application is still restricted by cost insufficient stability. Herein, a multi‐component electrocatalyst Ru nanoclusters on phosphorus‐doped/phosphate‐modified oxygen vacancy (O V )‐rich Fe/Fe O 4 composite nanorods (Ru@P‐Fe/Fe to synergistically promote electrocatalytic NO reaction RR)‐to‐NH performance strong metal‐support interaction (SMSI) reported. Impressively, the best Ru@P‐Fe/Fe catalyst exhibits outstanding RR activity, selectivity, durability in 0.1 M KNO + 0.5 KOH solution, with an NH yield rate 14.37 ± 0.21 mg NH3 h −1 cm −2 (1710.71 25 at −0.75 versus reversible hydrogen electrode (vs. RHE), Faradaic efficiency (FE) 97.2% −0.55 vs. RHE, superior stability over 50 h, suppressing most reported Fe‐based Ru‐based electrocatalysts. The characterizations theoretical calculations unveil that SMSI between P‐Fe/Fe can generation , tune electronic structure species, stabilize nanoclusters, thereby reducing energy barrier RR‐to‐NH inhibiting competitive evolution reaction, boosting FE,

Electrocatalytic nitrate reduction reaction offers a sustainable approach to treating wastewater and synthesizing high-value ammonia under ambient conditions. However, electrocatalysts with low faradaic efficiency selectivity severely hinder the development of nitrate-to-ammonia conversion. Herein, Ru-doped ultrasmall copper nanoparticles loaded on carbon substrate (Cu-Ru@C) were fabricated by pyrolysis Cu-BTC metal-organic frameworks (MOFs). The [email protected] catalyst exhibits high (FE) 90.4% at -0.6 V (vs RHE) an yield rate 1700.36 μg h
