Abstract

In this study the graphitic order of carbon nano structures formed on the cathode during electric arc discharges using a thin electrode with Ni were characterized by Scanning electron microscopy, X-ay diffraction and Raman spectroscopy. The results suggest that more ordered carbon nan o structure s are produced when the AC arc discharge method is used for carbon nano tubes synthesis. Moreover, the more Ni contains the thin electrode, the more ordered phases are obtained, independent of the elect ric arc discharge method used. Further on, it can be expected that various types of carbon nanostructures besides multiwalled carbon nanotubes (MWCNTs) co exist in the plasmogenic product obtained.
