To tackle the challenge in electrochemical nitrogen fixing and reduction aqueous electrolytes, conventional approach has been to suppress competitive hydrogen evolution reaction. Nonetheless, proton provision is a crucial step pathway produce ammonia, single active site faces daunting task striking balance between high fixation efficiency fast protonation kinetics. This work presents harmonic strategy featuring atomically dispersed dual Fe-Mo sites anchored an N-doped carbon (FeMoNC) substrate, where low-spin Fe center with enriched empty d orbitals aids activation, adjacent Mo accelerates kinetics of N-containing intermediates at via distal associative mechanism. Driven by this co-catalytic mechanism, FeMoNC catalyst achieves Faradaic 37.42%, marking significant improvement 7.8- 10.6-fold over or single-atom catalysts, respectively. Furthermore, excellent NH3 yield 54.40 μg h-1 mgcat.-1 realized flow cell enhancing mass transfer. study provides valuable insights into diatomic mechanisms for ammonia synthesis.

The electrocatalytic nitrogen reduction reaction (ENRR) offers a sustainable and promising approach for synthesizing ammonia under ambient conditions, providing an alternative to conventional industrial processes. However, challenges such as the inherent inertness of N2 competing hydrogen evolution (HER) in aqueous electrolytes hinder yield Faradaic efficiencies. This research use TiO2-supported Cu4Cl4(PPh3)4 Ag4Cl4(PPh3)4 nanoclusters (NCs) with quasi-cubic M4Cl4 cores (M = Ag or Cu) ENRR investigations. results reveal that NCs achieved 4.25 μg·h-1·cm-2 efficiency (FE) 53.0% at -0.9 V vs RHE. In contrast, produced 3.60 FE 51.39% -0.8 Both on TiO2 support demonstrated superior performance compared their unsupported counterparts, underscoring critical role improving electron transfer fostering synergistic effects, thereby boosting catalytic activity. important insights into design supported high-performance catalysts, advancing development environmentally energy-efficient approaches production.

Abstract Chemical looping technology utilizes the redox process and catalytic effects of metal oxides to convert carbon‐containing fuels carbon dioxide into value‐added chemicals. Currently, cation diffusion, sintering, agglomeration, inactivation during cyclic reactions are key challenges hindering widespread industrialization chemical looping. While encapsulation strategies using supports have shown potential for prolonging catalyst lifespan, fundamental mechanisms support‐redox interactions deactivation pathways under prolonged cycling remain elusive. In this study, varying structural evolution catalysts from in situ transmission electron microscopy (TEM) indicate that SiO 2 shell can suppress Ostwald ripening reduction through a confinement effect, thereby preventing agglomeration particles. Moreover, activity‐related size‐dependent Ni nanoparticles is elucidated density functional theory (DFT) simulations. support affects migration path oxidation process. Finally, struggle stably embedded within or securely anchored on their surfaces. The continuous separation between Ni‐Fe may serve as critical factor long‐term. This study offers new insights designing hierarchical with enhanced thermal stability observation actual reaction high‐temperature.
