Abstract: Interconnected mesoporous carbon sheets (IMCSs) for use in supercapacitors were fabricated from coal tar pitch using a metal-organic framework (MOF-5) template method combined with KOH activation.The samples were characterized by transmission electron microscopy,N₂ adsorption,X-ray diffraction and X-ray photoelectron spectroscopy.Results show that the specific surface area of IMCSs is in the range of 860 to 1 046 m²·g^-1.The IMCS prepared under the optimal conditions presents a high specific capacitance of 242 F·g^-1 at 0.05 A·g^-1 in a 6 M KOH aqueous electrolyte.It also exhibits an excellent rate capability with a 80.2% capacitance retention rate as the current density increases from 0.05 to 20 A·g^-1,and a cycle stability with a 94.2% capacitance retention rate after 10 000 charge-discharge cycles.The good electrochemical performance is ascribed to small hierarchical pores for ion fast transport,abundant accessible micropores for ion storage and interconnected structure for high electron conductivity.This work provides a simple method for the synthesis of IMCSs from cheap polycyclic aromatic hydrocarbons,including coal tar pitch and petroleum pitch,for use in high-performance supercapacitors.
