Catalyst of Ni and Co dependencies for carbon nanotube synthesis by CVD method

In this research, the effect of catalyst type on the CNTs synthesis was investigated. The carbon nanotubes (CNTs) were produced on stainless steel substrates and two of catalyst with different characteristics by using Thermal chemical vapor deposition (TCVD) method. The catalysts have the important role for the growth carbon nanotubes (CNTs). Acetylene gas (C2H2) diluted by NH3 was used as the reaction gas as a source of carbon. The formation of carbon nanotube structures were confirmed by Raman spectroscopy and scanning electron microscopy (SEM) methods. It was found that the type of catalyst play has an important role on the quality of the nanotubes.
