Abstract Electrochemical conversion of nitrate, a prevalent water pollutant, to ammonia (NH 3 ) is delocalized and green path for NH production. Despite the existence different nitrate reduction pathways, selectively directing reaction pathway on road now hindered by absence efficient catalysts. Single‐atom catalysts (SACs) are extensively investigated in wide range catalytic processes. However, their application electrocatalytic (NO − RR) infrequent, mostly due pronounced inclination toward hydrogen evolution (HER). Here, Ni single atoms electrochemically active carrier boron, nitrogen doped‐graphene (BNG) matrix modulate atomic coordination structure through boron‐spanning strategy enhance performance NO RR designed. Density functional theory (DFT) study proposes that BNG supports with ionic characteristics, offer surplus electric field effect as compared N‐doped graphene, which can ease adsorption. Consistent theoretical studies, as‐obtained NiSA@BNG shows higher activity maximal yield rate 168 µg h −1 cm −2 along Faradaic efficiency 95% promising electrochemical stability. This reveals novel ways rationally fabricate SACs' tunable electronic properties performance.

Atomically precise metal nanoclusters (NCs) are emerging as idealized model catalysts for imprecise nanoparticles to unveil their structure-activity relationship. However, the directional synthesis of robust NCs with accessible catalytic active sites remains a great challenge. In this work, we achieved bulky carboranealkynyl-protected copper NCs, monomer
