Abstract
Metal-organic frameworks (MOFs) have been extensively used as precursors or templates for the preparation of metal oxide/metal sulfides, bimetal oxide/metal sulfides, porous carbons (PCs), and corresponding nanocomposites for high-performance electrodes materials in the application of supercapacitors, where the morphologies of MOF-derived nanostructures have been made at the nanometer scale. This is used to be a vital role to improve the knowledge for the relationship between morphology and energy storage performances. The MOF-derived electrode materials can be divided into three groups in this chapter, including MOF-derived metal oxide/sulfide, MOF-derived PC, and MOFs supported composites. Generally, MOFs-derived porous nanostructure electrodes show high surface area, good electrical conductivity, and outstanding electrochemical stability. Meanwhile, MOFs-derived materials still suffer from the complicated synthesis process and unstable structure in a highly corrosive electrolyte. The recent progress for significant attention in the development of MOFs-derived porous nanocomposites electrode materials have been reviewed for the next-generation asymmetric supercapacitor applications.
