Electrocatalytic water splitting is a sustainable way to produce hydrogen energy, but the oxygen evolution reaction (OER) at the anode has sluggish kinetics and low energy conversion efficiency, which is the major bottleneck for large-scale hydrogen production. The design and synthesis of robust and low-cost OER catalysts are crucial for the OER. NiCo-based electrocatalysts have suitable atomic and electronic structures, and show high activity and stability during the OER process. Recently, significant progress has been made in regulating the structure and composition of NiCo-based catalysts and understanding the nature of catalysis, especially the OER mechanism, catalytic active sites, and structure–activity relationship. In this work, we summarized and discussed the latest development of NiCo-based electrocatalysts in the OER, with particular emphasis on catalyst design and synthesis, strategies for boosting OER performance, and understanding the nature of catalysis from experimental and theoretical perspectives. The OER mechanism, some activity descriptors, and atomic and electronic structure–activity relationships based on NiCo-based electrocatalysts are unveiled. Finally, some challenges and futuristic outlooks for improving the performance of NiCo-based electrocatalysts are proposed, and we hope this review can provide guidance for the design of more efficient NiCo-based electrocatalysts.

用于碱性析氧反应的镍钴基电催化剂：综述

电催化分解水是一种可持续的制氢方式，但阳极析氧反应（OER）动力学缓慢，能量转换效率低，是大规模制氢的主要瓶颈。设计和合成耐用且低成本的 OER 催化剂对于 OER 至关重要。NiCo基电催化剂具有合适的原子和电子结构，在OER过程中表现出高活性和稳定性。近年来，在调控 NiCo 基催化剂的结构和组成以及理解催化性质，尤其是 OER 机制、催化活性位点和构效关系方面取得了重大进展。在这项工作中，我们总结和讨论了 OER 中 NiCo 基电催化剂的最新进展，特别强调催化剂的设计和合成、提高 OER 性能的策略，以及从实验和理论的角度理解催化的性质。揭示了基于 NiCo 基电催化剂的 OER 机制、一些活性描述符以及原子和电子结构-活性关系。最后，提出了提高镍钴基电催化剂性能的一些挑战和未来展望，我们希望这篇综述能为设计更高效的镍钴基电催化剂提供指导。并揭示了基于镍钴基电催化剂的原子和电子结构-活性关系。最后，提出了提高镍钴基电催化剂性能的一些挑战和未来展望，我们希望这篇综述能为设计更高效的镍钴基电催化剂提供指导。并揭示了基于镍钴基电催化剂的原子和电子结构-活性关系。最后，提出了提高镍钴基电催化剂性能的一些挑战和未来展望，我们希望这篇综述能为设计更高效的镍钴基电催化剂提供指导。
