Abstract: Ordered mesoporous carbons were synthesized from asphaltene and preasphaltene derived from coal liquefaction residue by a template technique with KIT-6 as template. The microstructures of the as-made OMCs were characterized by XRD, TEM and nitrogen adsorption techniques. The electrochemical performance of OMCs as electrodes of supercapacitor was investigated by cyclic voltammetry and galvanostactic charge-discharge techniques. The results show that the as-made OMCs have ordered three-dimensional cubic mesostructure, and exhibit excellent ideal electric double layer behavior. carbon; supercapacitors
