چکیده مقاله :

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