Construction of 2D covalent organic framework and graphene oxide hybrids as high-performance capacitive materials

Abstract

A series of hybrid materials (a-GO@COF-Fs) were obtained by in situ growth of a two-dimensional covalent organic framework (COF-F) with strong electronegativity on the surface of aniline-functionalized graphene oxide (a-GO). It was found that the specific capacitance of a-GO@COF-F-5 is 295 F g⁻¹, which is a four-fold increase over pristine COF-F (71 F g⁻¹).
