| 面对日益严峻的环境问题，我国提出了“碳中和、碳达峰”的宏伟目标，清洁能源是实现双碳目标的有效手段之一。电解水制氢是一种制备清洁能源的重要方法，然而，电解水过程中析氧反应的缓慢动力学和较高过电位是妨碍水裂解效率的关键因素。金属–有机骨架材料（metal-organic framework，MOF）由于其规整的微观结构、较大的比表面积和可调的孔径等优点，被认为是电解水制氢的优异催化剂。综述了MOF材料用于催化析氧反应的最新研究进展，分析了该类材料的设计策略和催化机制。系统归纳了MOF基催化剂的各种调制策略，包括结晶度调制、电子调制、缺陷调制以及形态调制，并且对MOF材料作为析氧反应催化剂面临的挑战和机遇做出了展望。 |

| With the increasing environmental crisis, the Chinese government has put forward the grand goal of "carbon neutrality, carbon peak", and clean energy is one of the effective means to achieve the double carbon goal. However, high overpotential and slow kinetics of anodic oxygen evolution reaction (OER) are the primary obstacle for improving the efficiency of water splitting to produce hydrogen by water electrolysis. Metal-organic framework (MOF) are considered as excellent catalysts for water splitting due to their regular microstructures, large specific surface area, and tunable pore size, etc. In this paper, recent research progress of MOF-based electrocatalysts for OER has been reviewed by design strategy and catalytic mechanism of MOF-based electrocatalysts. Various modulation strategies for improving the activity of MOF-based electrocatalysts, including crystallinity, electronic structure, defect and morphology, were introduced. Finally, the challenges and opportunities of MOF materials as OER catalysts are prospected. |
