Application of Co3O4/nitrogen-doped carbon composite electrode material derived form Zeolitic imidazolate frameworks-67 in supercapacitors
H Wang, W Li, D Liu, G Liu, X An, J Liu, C Zhou… - Journal of …, 2023 - Elsevier
Metal-organic frameworks with high specific surface area and controlled morphology have
great potential for lithium-ion battery applications. Here, the ZIF-67 precursor was prepared
by the room temperature stirring method. Then Co 3 O 4/NC composite electrodes with
hollow polyhedral structure were successfully prepared by a two-step calcination method,
and their electrochemical properties were discussed. The specific capacitance of Co 3 O
4/NC at a current density of 1 A g− 1 is 1144F g− 1 (much higher than the specific …
