“…Interestingly, all such good features of the parent material were shown to be preserved in the MOF-derived TMS materials, providing the most needed properties for supercapacitor applications. 6,52–78 These electrode materials have been designed to explore the easy preparation and structural stability while overcoming the poor conductivity of precursor MOFs responsible for poor electrochemical performances and cycling stability during the operation of assembled energy devices. 13 Additionally, many of the MOF-derived materials present hollow nanostructures, which combine the advantages of both the ordered high porosity and thin pore walls of the precursor MOF structure.…”

“…In 2012, Chen and coworkers reported 1-D poly (ethylene glycol)-b-poly(4-vinylpyridine) (PEG-b-P4VP) nanowires composed of a PEG shell and slightly crosslinked P4VP core [28] When the aspect ratio of nanowires is high enough, the 3-D intertwining network can be formed. The follow-up research confirmed that the PEG-b-P4VP intertwined nanowires are excellent templates for the nucleation and growth of small MOF crystals due to their high aspect ratio (an average diameter of 30 nm and length up to several microns) and original abundant nucleation sites for metal ions [29] In the electrochemical application, the construction of complex intertwined conductive networks is desired, which would provide fast transport pathways for mass and charge, and then enhance the performance of catalysts [30,31] It is likely that a TMSs/carbon composite intertwining network could be prepared by the vulcanization of the as-prepared PEG-b-P4VP@MOFs network; but this hypothesis remains unexplored.…”

“…In particular, TMSs derived through a sacrificial template method by using a metal-organic framework (MOF) as the precursor can not only control the material morphology better than other methods, but also have high porosity, large specific surface area and a hollow structure. 12,14 In this regard, MOF-derived TMSs have been widely explored as electrode materials for SCs. For example, Jiang et al first reported a hollow CoS nanocage by simple sulfidation of the zeolitic imidazolate framework-67 (ZIF-67) template in the presence of thioacetamide (TAA).…”
