摘　　要：以合成树脂为前躯体,模板法制备一系列孔径分布较集中的介孔活性炭,利用氮气吸附与扫描电镜(SEM)表征其结构与形貌。通过循环伏安、恒流充放电及漏电流等电化学测试考察活性炭的电容特性。该系列活性炭用作电极材料具有较理想的双电层电容特性。其中样品AC07大电流充放电下,比电容达214.7 F/g,充放电效率保持在87%以上。A series of mesoporous activated carbons with narrow pore size distribution have been prepared via template method using synthetic resin as carbon precursor.The structure and morphology of the samples were characterized by N2 adsorption and scanning electron microscopy（SEM）.The capacitance properties of the carbons have been determined by cyclic voltammetry,charge-discharge in a constant current and leakage current.The carbons show ideal capacitance properties.When charge and discharge with high current density,the specific capacity of sample AC07 was 214.7 F/g,and the efficiency remains above 87 %.
