Carbon nanofibers by electrospun for high-performance supercapacitors

Recently, metal-organic frameworks (MOFs) have been regarded as an ideal precursor for preparing nanoporous carbon materials for the electrodes of supercapacitors due to their ability to tune the material’s structure from the molecular scale. However, the MOF-derived carbons usually exhibit a low graphitization level and large interface resistance between the particles which yield a poor electrical conductivity of the electrode disc that greatly limits their electrochemical performance. Herein, we demonstrate that pyrolysis of ZIF-67 that is embedded
