Single-atom Fe-N-C catalysts have attracted significant attention in the NOx reduction reaction (NOxRR). However, origin of their selectivity NOxRR remains unclear, impeding further advancements application. Herein, we investigate potential-driven competitive mechanism for NH3 and NH2OH production over single-atom pyridinic-FeN4 pyrrolic-FeN4 sites using constant-potential density functional theory calculations. The is linked to switching Fe 3d orbitals as they interact with intermediates. between determined by applied potentials. predominantly generates at higher potentials (-0.6 -1.2 V, vs SHE), while favored lower (0.6 -0.6 V). shows a similar potential-dependent product distribution, crossover potential -1.0 V. selectivity-determining intermediates (SDIs) are *NH2OH *NH2 + *OH. governed interacting SDIs, from dumbbell-shaped 3dz2 four-leaf clover-like 3dxz, 3dyz, 3dx2-y2, which plays crucial role controlling distribution based on These findings offer new insights into NOxRR.

Abstract Nano‐single‐atom‐catalysts have the potential to combine respective advantages of both nano‐catalysts and single‐atom‐catalysts thus exhibit enhanced performance. Generally, separation active sites in space limits interaction between single atoms nanoparticles. Heterointerface engineering has break this limitation. Regretfully, studies on interface effect nanoparticles are rarely reported. Herein, an unprecedented nano‐single‐atom heterointerface composed Fe single‐atoms carbon‐shell‐coated FeP (Fe SAC/FeP@C) is demonstrated as efficient electrocatalyst for nitrate reduction process from alkaline acidic. Compared with typical nano‐single‐atom‐catalysts SAC/FePO 4 ) SAC), constructed SAC/FeP@C heterostructure exhibits dramatically nitrate‐to‐ammonia Especially acidic media, maxmium Faradaic efficiency ammonia (NH 3 can reach 95.6 ± 0.5%, a maximum NH yield 36.2 3.1 mg h −1 cat (pH = 1.2), which considerably higher than previously Density functional theory calculations situ spectroscopic investigations indicate that unique charge redistribution at interface, together optimized electronic structure single‐atoms, strengthens intermediate adsorption catalytic activity. This work provides feasible strategy designing heterointerfaces, well valuable insights into conversion under environmentally relevant wastewater conditions.
