摘要：

The developing of a thermal plasma jet (TPJ) system to produce controlled carbon nanotube (CNT) in a continuous process was investigated. High-purity single-, double- and multi-walled carbon nanotubes were synthesized selectively over catalysts by varying the inlet location of carbon source, with or without H2 gas. Typical HRTEM images of the CNT produced and Fe particles collected were developed. It was also found that the size of the particles increased with the time because of the number of particles.
