چکیده
The low energy densities of supercapacitors are generally limited by the used anodes. To develop with high densities, metal–organic framework (TRD-ZIF-8) derived honeycomb-like porous zinc carbodiimide (ZnNCN) based nanocomposites (HPZC) surface loaded graphitized carbon nitride (g-C3N4) synthesized. After their detailed characterization means electron microscopy, spectroscopy and electrochemical techniques, materials to prepare asymmetric supercapacitor cells (HPZC-4//AC ASCs) HPZC-4 active as electrodes, which demonstrate power 7839 W Kg?1 213 Wh Kg?1, respectively. unique structure HPZC a 2D material improves charge/mass transport efficiency reduces ion diffusion resistance, contributing specific capacitance 779 F g?1 at current density 3 A g?1. study thus presents new way design transition metal assesses potential application electrodes in supercapacitors.
