摘　　要：A series of ordered mesoporous carbons have been synthesized via a simple template method using mesopore silica molecular sieve SBA-15 as template and commercial available phenol-formaldehyde resin as carbon precursor. The samples were characterized by X-ray diffraction(XRD), transmission electron microscopy (TEM) and nitrogen adsorption. The order and the specific surface area of the mesoporous carbon can be adjusted by the concentration of the resin. When the concentration was fixed at 0.15 g·mL-1, the highest order and the largest specific surface area of 1 017 m2·g-1 were obtained. The Cyclic Voltammetry(CV)test result shows that the specific capacitance of C0.15 sample is 222 F·g-1, when the scanning rate is 2 mV·s-1; and 159 F·g-1 when the scanning rate increases to 50 mV·s-1. Due to the differences of the pore structure, the ordered mesoporous carbons have better electrochemical capacitance than the activated carbon.A series of ordered mesoporous carbons have been synthesized via a simple template method using mesopore silica molecular sieve SBA-15 as template and commercial available phenol-formaldehyde resin as carbon precursor.
