SYNTHESIS OF CARBON NANOTUBES BY ELECTRIC ARC METHOD

The electric arc method is one of the most important methods in synthesizing carbon nanotubes, in addition to laser ablation method and catalytic decomposition of hydrocarbons. The recent progresses in the research of preparing carbon nanotubes by electric arc method are overviewed. Moreover, a semi continuous hydrogen electric arc method developed recently was introduced, by which single walled carbon nanotubes with high purity can be synthesized in a large scale.
