  • 摘要: 经混酸HNO3/H2SO4氧化后,煅前针状焦(GNC)转化为两种中间体,根据中间体在水中的分散能力区分为水可分散部分和水不可分散部分。这两种中间体均可经KOH活化后制得纳米多孔炭材料。通过XPS、XRD、低温N2吸脱附和TEM表征表明,在相同的KOH用量下,所得纳米多孔炭的孔结构不同,主要是由于两种中间体在表面性质和微结构方面的差异所致。以6mol/L KOH为电解液, 从水可分散中间体制得的多孔炭GNC-A10-3在40A/g下的质量比容量为248F/g,且倍率性能优异,C40/0.05为76%;而同样为3倍碱炭比时从水不可分散中间体制备的多孔炭GNC-R10-3在体积比电容上的电化学表现优于GNC-A10-3。
