在900℃不锈钢容器中，用氢氧化钾活化活化的活化介碳微珠（AMCMBs）混合制备了大量的碳纳米管（CNTs），并采用特殊的石油焦粉埋埋保护方法对活化过程进行保护。CNTs的直径约为50 nm，特征长度大于10 μ m。此外，AMCMBs/CNTs化合物作为电化学双层电容器的电极材料，在6 m KOH水溶液中表现出243 F g（-1）的比电容。(C) 2009 Elsevier b.v.版权所有
A large number of carbon nanotubes (CNTs) have been produced commingled in activated mesocarbon microbeads (AMCMBs) activated by potassium hydroxide in a stainless steel container at 900 degrees C, in which an especial buried-protection method with petroleum coke powders was used to protecting the product during activation. The CNTs were found to be about 50 nm in diameter and characteristic length more than 10 mu m. In addition, the AMCMBs/CNTs compound when used for electrode material of electrochemical double-layer capacitors exhibited a specific capacitance of 243 F g(-1) in 6 M KOH aqueous solution.
