Rational design and synthesis of efficient metal-organic frameworks (MOFs) as electrode modifiers for energy-related electrocatalytic applications are crucial for the development of clean-energy technologies. The present review focuses on recent work on robust earth-abundant heterogeneous catalysts based on pristine MOFs for the hydrogen evolution reaction (HER) and overall water splitting. These catalysts have been extensively studied as alternatives for noble metal-based ones, demonstrating "hydrogen economy" development prospects. In addition, novel strategies to enhance the conductivity, chemical stability and efficiency of MOF-based electrocatalysts are discussed. The best electrocatalysts even surpass the achievements of the platinum group of metals and MOF-derived catalysts in catalytic performance. The electrolytic cells with MOF-modified electrodes demonstrated excellent catalytic activity and can deliver a high current density at a voltage lower than that using the precious metal-based Pt/C cathodes and IrO2 anodes. In this review article, current approaches to design such MOF and MOF-modified electrode materials are summarized and analyzed.
合理设计和合成高效金属有机框架材料（MOFs）作为与能源相关的电催化应用的电极修饰剂，对于清洁能源技术的发展至关重要。本综述聚焦于基于原始MOFs的用于析氢反应（HER）和全水分解的稳健且储量丰富的非均相催化剂的近期研究工作。这些催化剂作为贵金属基催化剂的替代品已得到广泛研究，展现出“氢能经济”的发展前景。此外，还讨论了提高MOF基电催化剂的导电性、化学稳定性和效率的新策略。最佳的电催化剂在催化性能上甚至超过了铂族金属和MOF衍生催化剂的成果。具有MOF修饰电极的电解池表现出优异的催化活性，并且在低于使用贵金属基Pt/C阴极和IrO2阳极的电压下能够提供高电流密度。在这篇综述文章中，总结并分析了当前设计此类MOF和MOF修饰电极材料的方法。
