| چکیده | ||
| In this investigation a simplified arc discharge apparatus was used to synthesize mullti-wall carbon nanotubes. Because of not requiring vacuum equipment, heat exchange system, active or inert gases, this method is found to be cheaper and simpler than traditional arc discharge in gas environment. Using this method, CNTs are produced by performing an arc discharge between two graphite electrodes which are submerged in an aqueous solution. In this article the effect of different catalysts on quality of CNTs by using NaCl solution as reaction environment were investigated and also different concentration of Ni-Mo as bimettalic catalyst were used in the synthesis of these structures. Products were examined and compared by scanning electron microscopy (SEM), Raman spectroscopy and transmission electron microscopy (TEM). | ||
