Abstract Using low and optimized magnetic field along with electric is a novel strategy to facilitate electrochemical nitrite reduction reaction (NO 2 RR). Herein, the assisted electrocatalytic ammonia synthesis employing spin‐thrusted β‐MnPc at 95 mT explored. The calculated rate of generation 16603.4 µg h −1 mg cat , which almost twice that nonpolarized manganese phthalocyanine (MnPc) catalyst. Additionally, Faradaic efficiency (FE) –0.9 V versus RHE found be 92.9%, significantly higher compared MnPc In presence external field, catalysts provide better electron transfer channel results in lower charge resistance hence performances. Density functional theory (DFT) result further verifies induced has potential barrier (0.51 eV) for protonation NO* than (1.08 eV), confirms enhanced ammonia.

Abstract Electrocatalytic N 2 oxidation reaction (NOR) is an environmentally sustainable approach to synthesize NO 3 − under mild conditions. Inspired by the ferriporphyrin (FePP) catalytic species in nitrite oxidoreductase, three FePP‐based biomimetic catalysts with different functional groups (─NH , ─H, and ─COOCH ) are designed prepared successfully. Theoretical calculations indicate that these can alter electron density of Fe center, affecting their ability adsorb activate . The strong electron‐donating ─NH group enhance iron sites, which reveals a maximum yield 728.55 µmol h −1 g FePP high Faradaic efficiency 10.6%.

Understanding the structure–activity relationship on a solid surface is crucial for developing an efficient low-temperature NH3–SCR catalyst. Herein, in-depth investigation was conducted single-atom Mn-doped α-Fe2O3 catalyst by combining experimental studies and density functional theory calculations. Mn doping not only facilitates N–H cleavage in Eley–Rideal (E–R) pathway but also promotes adsorption of NO N–O bond, lowering energy barrier rate-determining step Langmuir–Hinshelwood (L–H) pathway. Thus, catalytic reaction along both potential pathways, which reaction. Further analysis reveals that introduces unoccupied dxy orbital, interaction with π orbital NO, thereby augmenting adsorption. Moreover, redistributes electron density, enhancing flexibility electrons Fe atom facilitating transfer from to π* Mn–N–O, thus promoting cleavage. The present study demonstrates incorporation d orbitals appropriate symmetry d-π between dopant reactant, significantly efficiency. These findings provide valuable new insights into design high-performance catalysts.
