Abstract
Carbon nanomaterials have attracted vast attention due to the rising demand for various nanotechnology applications. The possibility of preparing multi-walled carbon nanotube (MWCNT) and graphene on large scale are demonstrated using direct current arc discharge with transverse magnetic field effect at low ambient pressure. In this work, we study, the effect of external transverse magnetic effect on structural perfection of graphene and multi-walled carbon nanotube. High quality carbon-nanotube were synthesized by arc discharge plasma in Hydrogen ambient at pressure 1 mbar in presence of external transverse magnetic field. The synthesized nanomaterials were characterized by electron microscopy, XRD and Raman Spectroscopy. A significant increase in the quantity and quality of carbon nanotube and graphene in the presence of transverse magnetic field during arc discharge process.
