摘　　要：采用微湿含浸法制备了一系列具有不同比表面积和孔径分布的超级电容器有序中孔炭材料,同时采用Al-SBA-15为模板剂制得具有六方排列的空心炭管CMK-5。所制得的有序中孔炭的BET比表面积随糠醇加入量的增加而减小。电化学性能测试结果表明,在1mA.cm-2的充放电电流密度下各中孔炭材料比电容的大小顺序与其BET比表面积的大小顺序相一致。在所有样品中AlSC-0.8由于具有最大的比表面积,因此其比电容最大,达87.8F.g-1。倍率性能测试结果表明,具有CMK-3结构的SC-2.0的倍率性能最好,在50mA.cm-2的放电电流密度下其放电比电容接近AlSC-0.8有序中孔炭的水平。A series of ordered mesoporous carbons used as electrode material for supercapacitor with different surface area and pore size distribution were prepared by incipient wetness impregnation method. And AISC-0. 8 with CMK-5 structure has been prepared by this method with AI-SBA-15 as template at the same time. The results of electrochemical characterization show that the magnitude order of the specific capacitance of the mesporous carbons is in good agreement with that of the BET surface area at the charge-discharge current density of 1 mA · cm-2. Ordered me.mesoporous carbon AISC-O. 8 exhibits the highest specific capacitance of 87. 8F ·g-l. The rate capability of ordered mesoporeus carbon SC-2.0 with CMK-3 structure is found to he the best.
