Abstract

Metal–organic frameworks (MOFs) are crystalline porous materials formed by the coordination of metal ions and organic linkers. MOFs have garnered considerable interest in energy storage, primarily for supercapacitor applications because of their exceptionally high surface area, tunable porosity, and structural versatility. This review highlights the electrochemical behavior of MOFs, their charge storage mechanisms, particularly electric double-layer capacitance and pseudo-capacitance, as well as their synthesis routes using solvothermal, microwave-assisted, and hydrothermal methods. Such enhancement of capacitance and rate capability results from the incorporation of MOFs with conductive materials such as graphene quantum dots and metal oxides. Specific cases involving Ni-MOF, Co-MOF, and NbSn-MOF composites are discussed, with a focus on their structural properties, electrochemical performance, and potential application prospects. Thereafter, the environmental sustainability aspects, challenges, and future directions of MOF-based supercapacitors are discussed.

超级电容器中MOF的电化学行为综述

金属有机骨架（mof）是金属离子与有机连接剂配位形成的晶体多孔材料。mof由于其超高的表面积、可调节的孔隙率和结构的通用性，在能量存储领域引起了相当大的兴趣，主要用于超级电容器的应用。本文综述了mof的电化学行为、电荷存储机制，特别是双层电电容和伪电容，以及溶剂热法、微波辅助法和水热法的合成路线。这种电容和速率能力的增强源于mof与导电材料（如石墨烯量子点和金属氧化物）的结合。讨论了Ni-MOF、Co-MOF和NbSn-MOF复合材料的具体案例，重点讨论了它们的结构特性、电化学性能和潜在的应用前景。然后，讨论了基于mof的超级电容器的环境可持续性方面、挑战和未来方向。

期刊介绍： The Journal of Organometallic Chemistry targets original papers dealing with theoretical aspects, structural chemistry, synthesis, physical and chemical properties (including reaction mechanisms), and practical applications of organometallic compounds. Organometallic compounds are defined as compounds that contain metal - carbon bonds. The term metal includes all alkali and alkaline earth metals, all transition metals and the lanthanides and actinides in the Periodic Table. Metalloids including the elements in Group 13 and the heavier members of the Groups 14 - 16 are also included. The term chemistry includes syntheses, characterizations and reaction chemistry of all such compounds. Research reports based on use of organometallic complexes in bioorganometallic chemistry, medicine, material sciences, homogeneous catalysis and energy conversion are also welcome. The scope of the journal has been enlarged to encompass important research on organometallic complexes in bioorganometallic chemistry and material sciences, and of heavier main group elements in organometallic chemistry. The journal also publishes review articles, short communications and notes.
