Abstract Fe–N–C catalysts are emerging as promising alternatives to Pt‐based for the oxygen reduction reaction (ORR), while they still suffer from sluggish kinetics due discontented binding affinity between Fe‐N 4 sites and oxygen‐containing intermediates, unsatisfactory stability. Herein, a flexible multichannel carbon fiber membrane immobilized with atomically dispersed neighboring Fe nanoclusters/nanoparticles (FeN ‐Fe NCP @MCF) is synthesized. The optimized geometric electronic structures of atomic brought by adjacent hierarchically porous structure matrix endow FeN @MCF outstanding ORR activity stability, considerably outperforming its counterpart only commercial Pt/C catalyst. Liquid solid‐state zinc–air batteries employing both exhibit durability. Theoretical calculation reveals that nanoclusters can trigger remarkable electron redistribution modulate hybridization central 3 d O 2 p orbitals, facilitating activation molecules optimizing adsorption capacity intermediates on sites, thus accelerating kinetic. This work offers an effective approach constructing coupling have single atoms coexisting efficient catalysis.

Abstract It is important to tune the coordination configuration of dual‐atom catalyst (DAC), especially in first sphere, render high intrinsic catalytic activities for oxygen reduction/evolution reactions (ORR/OER). Herein, a type atomically dispersed and boron‐coordinated DAC structure, namely, FeN 4 B‐NiN B dual sites, reported. In this incorporation boron into sphere /NiN atomic sites regulates its geometry electronic structure by forming “Fe‐B‐N” “Ni‐B‐N” bridges. The exhibits much enhanced ORR OER property compared ‐NiN counterparts. Density functional theory calculations reveal that boron‐induced charge transfer asymmetric distributions central Fe/Ni atoms optimize adsorption desorption behavior ORR/OER intermediates reduce activation energy potential‐determining step. Zinc‐air batteries employing cathode exhibit maximum power density (236.9 mW cm −2 ) stable cyclability up 1100 h. result illustrates pivotal role first‐coordination DACs tuning electrochemical conversion storage activities.

Abstract Advancements in single-atom-based catalysts are crucial for enhancing oxygen evolution reaction (OER) performance while reducing precious metal usage. A comprehensive understanding of underlying mechanisms will expedite this progress further. Here we report Ir single atoms coordinated out-of-plane with dimethylimidazole (MI) on CoFe hydroxide (Ir 1 /(Co,Fe)-OH/MI). This /(Co,Fe)-OH/MI catalyst, which was prepared using a simple immersion method, delivers ultralow overpotentials 179 mV at current density 10 mA cm −2 and 257 600 as well an ultra-small Tafel slope 24 dec −1 . Furthermore, has total mass activity exceeding that commercial IrO 2 by factor 58.4. Ab initio simulations indicate the coordination MI leads to electron redistribution around sites. causes positive shift d -band centre adjacent Co sites, facilitating optimal energy pathway OER.
