Abstract

Metal–air batteries, fuel cells, and electrochemical H2O2 production currently attract substantial consideration in the energy sector owing to their efficiency and eco-consciousness. However, their broader use is hindered by the complex oxygen reduction reaction (ORR) that occurs at cathodes and involves intricate electron transfers. Despite the significant ORR performance of platinum-based catalysts, their high cost, operational limitations, and susceptibility to methanol poisoning hinder broader implementation. This emphasizes the need for efficient non-precious metal-based ORR electrocatalysts. A promising approach involves utilizing single-atom catalysts (SACs) featuring metal–nitrogen–carbon (M-N-C) coordination sites. SACs offer advantages such as optimal utilization of metal atoms, uniform active centers, precisely defined catalytic sites, and robust metal–support interactions. However, the symmetrical electron distribution around the central metal atom of a single-atom site (M-N4) often results in suboptimal ORR performance. This challenge can be addressed by carefully tailoring the surrounding environment of the active center. This review specifically focuses on recent advancements in the Fe-N4 environment within Fe-N-C SACs. It highlights the promising strategy of coupling Fe-N4 sites with metal clusters and/or nanoparticles, which enhances intrinsic activity. By capitalizing on the interplay between Fe-N4 sites and associated species, overall ORR performance improved. The review combines findings from experimental studies and density functional theory simulations, covering synthesis strategies for Fe-N-C coupled synergistic catalysts, characterization techniques, and the influence of associated particles on ORR activity. By offering a comprehensive outlook, the review aims to encourage research into high-efficiency Fe single-atom sites coupled synergistic catalysts for real-world applications in the coming years.

促进氧还原反应的 Fe-N-C 单原子位点耦合协同催化剂的最新研究进展
金属空气电池、燃料电池和电化学 H2O2 生产因其高效性和生态意识,目前在能源领域受到广泛关注。然而,由于阴极发生复杂的氧还原反应(ORR),且涉及错综复杂的电子转移,阻碍了它们的广泛应用。尽管铂基催化剂具有显著的 ORR 性能,但其高昂的成本、操作上的局限性以及易受甲醇毒害的特性阻碍了其广泛应用。这就强调了对高效的非贵金属基 ORR 电催化剂的需求。一种很有前景的方法是利用具有金属-氮-碳(M-N-C)配位位点的单原子催化剂(SAC)。单原子催化剂具有金属原子利用率高、活性中心均匀、催化位点精确定位以及金属与支撑物相互作用强等优点。然而,单原子配位(M-N4)中心金属原子周围的对称电子分布往往会导致 ORR 性能不理想。这一难题可以通过精心调整活性中心的周围环境来解决。本综述特别关注 Fe-N-C SAC 内 Fe-N4 环境的最新进展。它强调了将 Fe-N4 位点与金属团簇和/或纳米粒子耦合的有前途的策略,这种策略可提高固有活性。通过利用 Fe-N4 位点与相关物种之间的相互作用,整体 ORR 性能得到了改善。综述结合了实验研究和密度泛函理论模拟的结果,涵盖了 Fe-N-C 耦合协同催化剂的合成策略、表征技术以及相关粒子对 ORR 活性的影响。通过提供一个全面的展望,该综述旨在鼓励在未来几年内研究用于实际应用的高效铁单原子位点耦合协同催化剂。
