“…They found that bimetallic FeNi catalysts are superior to atomically dispersed single Fe and Ni catalysts in terms of reversible OER and ORR performance. Similar results were verified by Ma et al, Fe sites with neighboring Ni were responsible for both ORR and OER, as suggested by DFT simulations and in-situ Raman [ 53 ]. Recent studies have attributed the greater bifunctionality to synergistic interactions between bimetal atoms.…”

“…Recently, it has been demonstrated that the M-N-C with bimetal atoms can significantly improve the electrocatalytic performance compared with the single-metal M-N-C [ 53 , 69 , 125 , 126 ]. The introduction of secondary metal atoms can raise the opportunity to increase flexibility and concentrate different activities toward ORR and OER [ 43 , 127 ].…”

Rechargeable zinc-air batteries (ZABs) are currently receiving extensive attention because of their extremely high theoretical specific energy density, low manufacturing costs, and environmental friendliness. Exploring bifunctional catalysts with high activity and stability to overcome sluggish kinetics of oxygen reduction reaction and oxygen evolution reaction is critical for the development of rechargeable ZABs. Atomically dispersed metal-nitrogen-carbon (M-N-C) catalysts possessing prominent advantages of high metal atom utilization and electrocatalytic activity are promising candidates to promote oxygen electrocatalysis. In this work, general principles for designing atomically dispersed M-N-C are reviewed. Then, strategies aiming at enhancing the bifunctional catalytic activity and stability are presented. Finally, the challenges and perspectives of M-N-C bifunctional oxygen catalysts for ZABs are outlined. It is expected that this review will provide insights into the targeted optimization of atomically dispersed M-N-C catalysts in rechargeable ZABs.

Multiatom catalysts (MACs) with isolated monodisperse active sites comprising two to tens of metal atoms have attracted intensive research attention and industrial interest. With the combination of high atom utilization and well‐defined molecule‐like electronic structure, MACs show great potential for applications in a wide range of electrochemical catalytic reactions. This review aims to discuss the recent progress of MACs in energy‐related electrocatalysis. Critical issues, including the synthesis and characterization of the MACs, will be showcased. Moreover, recent advances are highlighted in the design and synthesis of MACs with a well‐controlled structure and composition to achieve enhanced catalytic performance in energy‐related electrocatalysis. Current challenges and future prospects for MACs are also presented to shed light on the rational design of MACs as potential industrialized catalysts in the future.
