Abstract Crystalline γ‐FeO(OH) dominantly possessing ─ OH terminals (𝛾‐FeO(OH) c ), polycrystalline containing multiple O, OH, and Fe pc α‐Fe 2 O 3 majorly surface are used as electrocatalysts to study the effect of on electrocatalytic nitrate reduction reaction (eNO RR) selectivity stabilization intermediates. Brunauer‐Emmett‐Teller analysis electrochemically determined area suggest a high active 117.79 m g −1 (ECSA: 0.211 cm ) for 𝛾‐FeO(OH) maximizing accessibility adsorption exhibiting selective eNO RR NH at pH 7 with yield rate 18.326 mg h −2 , >85% Faradaic efficiency (FE), least nine‐times catalyst‐recyclability. 15 N‐ D‐labeling combined in situ IR Raman studies validate ions generation nitrite hydroxyl amine A kinetic isotope (KIE) value 2.1 indicates H proton source proton‐coupled electron transfer rate‐limiting step.

This study reports a method for the selective reduction of NO3– and NO2– to N2 or NH3, extending prior work in our lab where was reduced NO by [N(afaCy)3Fe]OTf2 (N(afaCy)3 = tris(5-cyclohexyl-amineazafulvene-2-methyl)amine, OTf triflate). The first pathway involves N2, generated initial step is transformed N2O PPh3 further complex. An alternative showcases bound complex, [N(afaCy)3Fe(NO)]2+, NH3 using chemical reductants, albeit with modest yield 29%. Confirmation nitrogen source as established through 15N labeling studies. Hydroxylamine (NH2OH) proposed plausible intermediate NO, supported independent NH2OH experiments computational Nature employs well-orchestrated, stepwise process involving several enzymes reduce N-containing oxyanions, this approach provides valuable insights into mechanisms nitrate nitrite, yielding product.

A sustainable reaction of electrocatalytic nitrate conversion in ammonia production (NO3RR) occurring under ambient conditions is currently prime interest, as well urgent research due to the real potential replacement environmentally unfavorable Haber-Bosch process. Herein, a series electrocatalysts based on two-component cobalt alloys was synthesized using low-cost non-noble metals Co, Fe, Cr, and also Si. The samples were characterized studied by following methods: SEM, EDX, XRD (both transmission reflection), UV-VIS spectroscopy, optical microscopy, linear (and cyclic) voltammetry, chronoamperometry, electrochemical impedance spectroscopy. Beyond that, determination electrochemically active surface area carried out for all electrocatalysts. Unexpectedly, sample having an intermetallic compound (IMC) composition Co2Si turned be most highly effective. highest Faradaic efficiency (FE) 80.8% at E = -0.585 V (RHE) yield rate 22.3 µmol h-1 cm-2 -0.685 indicate progressive role IMC main component electrocatalyst. Thus, this study demonstrates promise enormous efficient NO3RR. This work can serve primarily starting point future studies reactions catalysts containing metals.
