Abstract Simultaneously improving activity and stability is a crucial yet challenge in the development of metallic single‐atom‐based catalysts. In current work, novel approach introduced to address this issue by combining post‐adsorption secondary pyrolysis techniques create synergistic catalytic system, which single atoms (SAs) Fe sites played NC matrix (Fe─NC) are coupled with high‐entropy atomic clusters (HEACs). Theoretical calculations reveal that incorporation HEACs lead rehybridization 3d orbital configuration Fe‐N 4 , helps balance adsorption/desorption energy oxygenated intermediates. situ spectroscopy further reveals rate‐limiting step OH * desorption on HEAC/Fe─NC oxygen reduction reaction (ORR) more facile compared Fe─NC, implying higher ORR activity. Moreover, effect diffusion activation barriers entropy contributes structural HEAC/Fe─NC, resulting remarkable durability. Consequently, unique catalyst exhibits half‐wave potentials 0.927 0.828 V an aqueous solution KOH (0.1 m ) HClO ), respectively, along excellent The findings propose strategy for modulating electronic structure SAs catalysts enhancing their through strong interactions between HEACs.

Abstract The integration of atom clusters and single atoms into a unified system represents desirable approach for attaining enhanced catalytic performance. Nonetheless, the controllable synthesis single‐atom nanocluster integrated (SA‐NC) faces considerable challenges, mechanisms underlying activity remain poorly understood. In this research, cobalt‐based catalyst containing both coordinatively unsaturated (CoN 3 ) small nanoclusters (Co@SA‐NC) is synthesized. Co@SA‐NC not only facilitates charge mass transfer due to interconnected long‐range micromorphology, thus endowing efficient oxygen electrocatalytic reaction (ORR/OER), but also undergoes surface reconfiguration upon OH adsorption at high potentials in alkaline ORR/OER conditions. More appealingly, OH‐involved reconfigured adaptive structure promotes optimization energy barriers owing dynamic regulation from bridged between Co cluster whole process. Specific application metrics, zinc–air battery assembled using exhibit targeted power density enhancement with 270 mW cm −2 an medium. This work offers effective insight study SA‐NC pathways catalysis.

Abstract Oxygen electrochemistry, which encompasses the oxygen reduction reaction (ORR) and evolution (OER), is of utmost importance in energy‐related reactions such as zinc‐air batteries (ZABs). However, due to their four‐electron transfer process, these are still significantly restricted by sluggish kinetics. Supporting atomically‐dispersed (AD) catalyst or metal nanoparticles (NPs) on nitrogen‐doped carbon (NC) proven be an effective strategy for enhancing performance electrocatalysis. Nevertheless, types catalysts fails meet critical requirements ZABs. Herein, a novel Fe AD Co NPs @NC, consists both Fe‐N 1 sites lattice, developed. Spectroscopy studies density functional theory calculations indicate that site lattice facilitates conversion amorphous CoOOH, serves main active ORR. @NC demonstrates remarkable activity OER When it used air‐electrode ZABs, power 247.49 mW cm −2 . This work presents simple yet efficient method enhance electrochemical through synergy between NPs.
