Abstract

The anodic oxygen evolution reaction (OER) can be combined with various cathodic reactions to enable the electrochemical synthesis of diverse chemicals and fuels, particularly in water electrolysis for hydrogen production. It is however exhibiting a high overpotential due to the sluggish four-electron transfer process, which is considered the decisive reaction in energy conversion systems. In recent years, metal-organic frameworks (MOFs) have emerged as the ideal catalysts for accelerating OER. This is primarily because of their orderly porous architecture, structural tailorability, and compositional diversity. This review systematically summarizes the recent research progress in pristine MOF electrocatalysts for OER, which covers the construction strategies and electrocatalytic performance of more than eight types of MOFs. Additionally, the partial/complete structural reconstructions and their effects on MOF-based OER electrocatalysts are highlighted. In particular, the development process of “discovery, explanation, and utilization” for the structural reconstructions of MOF electrocatalysts is outlined. Furthermore, the catalytic mechanisms are elaborated in detail, aiming to provide insight into the rational design and performance optimization of MOF-based OER electrocatalysts. The challenges and future perspectives of MOF-based OER electrocatalysts for industrial applications are also discussed.

析氧反应电催化剂金属有机骨架的研究进展

阳极析氧反应（OER）可以与各种阴极反应相结合，以实现各种化学品和燃料的电化学合成，特别是在用于氢气生产的水电解中。然而，由于缓慢的四电子转移过程，它表现出高过电势，这被认为是能量转换系统中的决定性反应。近年来，金属有机骨架（MOFs）已成为加速OER的理想催化剂。这主要是因为它们有序的多孔结构、结构的可定制性和成分的多样性。本文系统总结了用于OER的原始MOF电催化剂的最新研究进展，涵盖了八种以上MOF的构建策略和电催化性能。此外，还强调了部分/完全结构重建及其对基于MOF的OER电催化剂的影响。特别是，概述了MOF电催化剂结构重建的“发现、解释和利用”的发展过程。此外，还详细阐述了催化机理，旨在为MOF基OER电催化剂的合理设计和性能优化提供见解。还讨论了MOF基OER电催化剂在工业应用中的挑战和未来前景。
