Sugar-derived ordered mesoporous carbon, OMC was prepared by infiltration of sugar into the porosity of SBA-15 template followed by carbonization in an inert ambience. The structure, porosity and surface characteristics of the OMC were evaluated using XRD, TEM and nitrogen physisorption analysis. The OMC obtained as replica of SBA-15 template possesses high BET surface area (~900 m2g1), pore size distribution in mesopores range and large pore volume (0.93 cm3g1). The electrochemical performance of the material in 1 M KOH aqueous electrolyte was investigated by cyclic voltammetry (CV), galvanostatic charge-discharge (CD) and electrochemical impedance spectroscopy (EIS). The influence of scan rate and current density were evaluated. The results showed high specific capacitance and good capacitance retention over high scan rate and current density. The OMC can be used as alternative electrode material in EDLC and supercapacitor application.
