MOFs-Derived Nanoarrays: A Promising Strategy for Next-Generation Supercapacitors

Abstract

Developing high-performance electrode materials for supercapacitors is one of the keys to improving their overall performance. Metal-organic framework (MOF) is a kind of crystalline porous material with periodic network structure, which is connected by inorganic metal centres and bridged organic ligands through self-assembly. It has the advantages of a large specific surface area, controllable pore size, excellent stability and ordered crystal structure. MOF-derived nanoarrays exhibit excellent electrochemical performance due to their unique structure, rich activation points, close interface contact, and easy electron migration and mass transfer, which have attracted extensive attention in supercapacitor applications. This study mainly reviews the synthesis methods of MOF array electrodes and their applications in supercapacitors. In addition, we also described the challenges and prospects of MOF-derived array electrodes in the application of supercapacitors. This paper has important reference value for the design of MOF-derived array electrodes and advanced energy storage systems. The progress of advanced energy storage systems will further promote the development of sustainable renewable energy, avoid adverse climate and greenhouse effect caused by excessive use of fossil fuels, and achieve a green energy future.
