摘　　要：利用电弧等离子体法以Co2O3为催化剂裂解甲烷制备得到了碳纳米管。所得固相产物进行了扫描电镜（SEM）和高分辨透射电镜（HRTEM）分析表征。结果表明：固相产物中形成的碳纳米管纯度较高，直径在50-90nm之间，并发现了一种特殊的管壁厚度不均，呈厚一薄厚形态的碳纳米管。Carbon nanotubes （CNTs） were produced by arc plasma jet by methane decomposed with dosing Co2o3 as catalyst. The products were characterized by scanning electron microscopy （SEM） and high resolution transmission electron microscopy （HRTEM）. The experimental results revealed that large scale and high purity carbon nanotubes were produced in the solid phase, with the diameter of the CNTs distributing in 50-90nm. And a carbon nanotube with uneven wall thickness was produced whose wall was symmetrical thick-thin-thick style.
