Modulating the Local Coordination Environment of M‐N_x Single‐Atom Site for Enhanced Electrocatalytic Oxygen Reduction

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 4, 2024

Abstract Efficient, durable, and economical oxygen reduction catalysts are key for practical applications such as fuel cells metal–air batteries. Single atom (SACs) have attracted sustained widespread attention owing to their unique electronic properties exceptional atomic utilization, positioning them promising electrocatalysts in energy conversion storage. However, the symmetric charge distribution of metal site M‐N 4 configuration SACs is not conducive electron transfer transport electrocatalytic reactions, resulting a low adsorption reaction (ORR) related species (*OH, *O, *OOH), which severely limits intrinsic activity electrocatalysts. To overcome this limitation improve durability, heteroatom doping can effectively modulate local coordination environment (LCE) atom, including coordinating atoms, shells number. These modifications significantly improved performance carbon supported with ORR. Based on this, thorough summary major progress made recent years adjusting LCE through heteroatoms provided perspective future development offered here.
