Preparation of MOF based porous carbon and its application in supercapacitor

Abstract

Abstract: Metal-organic framework materials (MOFs) have broad application prospects as precursors in electrochemical fields due to their high specific surface area, pore structure, and structural and functional diversity. In this paper, the metal-organic framework material [Zn₃(bpdc)₃(bpy)]·2DMF·4H₂O](ZBB) was synthesized by hydrothermal method, the porous carbon ZBBC-T-A was prepared by carbonization and activation method. The effects of different carbonization temperatures and different carbon base ratios on the microstructure and electrochemical properties of porous carbon were studied. The results showed that the porous carbon ZBBC-800-1∶3 is mainly microporous and mesoporous, and the maximum specific surface area is 2 294.6 m² ·g^-1. Using 6 mol·L^-1 KOH as electrolyte, the specific capacitance is 304.8 F·g^-1 the current density 1 A·g^-1. When the current density increases from1 A·g^-1 to 10 A·g^-1,the capacitance loss rate is 21.26%. At the current density of 1 A·g^-1, the capacitance retention is 95.85% after 5 000 cycles calculated energy density is 8.06 Wh·kg^-1.
