Abstract

Recently, single-atom catalysts (SACs) have been found to be promising candidates for oxygen electrocatalysis in rechargeable lithium–oxygen batteries (LOBs) owing to their high oxygen electrocatalytic activity and high stability, which originates from their unique coordination environments and electronic properties. As a new type of catalyst for LOBs, the advancements have never been reviewed and discussed comprehensively. Herein, breakthroughs in the design of various types of SACs as cathode catalysts for LOBs are summarized, including Co-based, Ru-based, and other types of SACs. Moreover, considerable emphasis is placed on the correlations between the structural feature of the SAC active sites and the electrocatalytic performance of LOBs. Finally, an overview and challenges of SACs for practical LOBs are also provided. This review provides an intensive understanding of SACs for designing efficient oxygen electrocatalysis and offers useful guidelines for the development of SACs in the field of LOBs.
锂氧电池单原子催化剂阴极研究进展
最近,单原子催化剂(SAC)被发现是可再充电锂-氧电池(LOBs)中氧电催化的有前途的候选者,因为它们具有高的氧电催化活性和高稳定性,这源于它们独特的配位环境和电子性质。作为一种新型的LOB催化剂,其进展从未得到全面的回顾和讨论。本文总结了在设计各种类型的SAC作为LOB的阴极催化剂方面的突破,包括Co基、Ru基和其他类型的SAC。此外,相当重视SAC活性位点的结构特征与LOB的电催化性能之间的相关性。最后,还提供了SAC对实际LOB的概述和挑战。这篇综述为设计有效的氧电催化提供了对SAC的深入理解,并为在LOB领域开发SAC提供了有用的指导。
