Mesoporous carbons have been synthesized using template method by polymerizing and then carbonizing carbon precursor of sucrose accommodated in novel templates of SAPO-11 and SAPO-34 after the removal of templates with NaOH solution (50 vol.% ethanol-50 vol.% H2O). High surface areas and excellent eletrochemical properties of the mesoporous carbons were identified by the Brunauer-Emmett-Teller method, cyclic voltammetry, electrochemical impedance spectroscopy and constant current charge-discharge tests. The surface areas of the sample carbons are the range of 950-975 m2/g, with a narrow pore size between 3.8 and 11.0 nm. The sample carbon derived from SAPO-11 exhibits better electrochemical performance over the one from SAPO-34, with the specific capacitance of 154.8, 113.5 F/g them, respectively, measured in 1 M KOH aqueous solution at the loading current density of 0.25 A/g.
