Abstract
We describe a method for the synthesis of multiwalled carbon nanotubes by AC arc discharge. The discharge is maintained in a magnetic field whose strength can be varied. The soot obtained was purified in several steps. The structure and morphology of the MWCNTs thus produced are characterized by using Transmission Electron Microscopy (TEM) and Raman Spectroscopy. The produced MWCNTs are found to be of high quality as seen from characterization results. However there is wide dispersion in outer diameter and number of walls.
