直流电弧等离子体热解甲烷制备纳米碳管

Carbon nanotubes(CNTs) were produced by pyrolysis of methane in DC arc argon plasma in the present study. TEM, ICP-CAS, TGA were used as analytical tools. Experimental results show that the CNTs grew on the chamber wall with multiwalled structure and various shapes. Another advantage of this method is that it can produce hydrogen simultaneously.
