Preparation And Characterization Of Multi-Walled Carbon Nano Tubes By Liquid Arc-Discharge Method
The paper reports the preparation and characterization of multiwall carbon nanotubes (MWCNT). The nanotubes
have been synthesized by an electric arc discharge performed in deionised water using graphite electrodes. The method
involves the application of a magnetic field which enhances the yield of carbon nano tubes. The carbon nanotubes (CNT)
have been produced under varying conditions of voltages and currents using different refluxing media. Transmission
Electron microscopy (TEM) observations reveal the morphological details of the nanotubes while Raman Spectroscopy has
been performed for their structural characterization.
