ZIF-derived nitrogen-doped carbon/3D graphene frameworks for all-solid-state supercapacitors

Author affiliations

Abstract

Nitrogen-doped porous carbons supported on three-dimensional (3D) graphene frameworks were prepared by decorating ZIF-8 or ZIF-67 onto graphene aerogels by a heterogeneous nucleation method and subsequent carbonization and etching processes. The resulting carbon composite exhibited a hierarchically porous structure and a high surface area of 207 m2 g−1. Due to the high electrical conductivity and high-rate transportation arising from graphene frameworks and nitrogen-doping, the ZIF-67 derived porous carbon/graphene composite (GA@CZIF-67-E) showed a high specific capacitance of 53 F g−1 at a scan rate of 5 mV s−1, and good cycle stability after 1000 cycles when applied in all-solid-state supercapacitors.
