In this study, electrical arc discharge method is used for the synthesis of multi wall carbon nanotubes (CNTs). The advantages of applied setup for producing CNTs are simplicity, low-cost procedures and avoiding the multistep purification. The experiments were optimized by submerging graphite electrodes inside deionized water and various concentrations of sodium chloride solution. The purpose of this research is to investigate the effect of liquid medium on growth, size and quality of the CNTs structures. The results show that CNTs of 150 A, A mu m length or larger with high purity and quality without using catalyst are produced on the cathode surface. Furthermore, the quantity of CNTs is influenced by NaCl concentration. Scanning electron microscopy, Raman spectroscopy and X-ray diffraction technique were used to characterize the results.
