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).

متن کاملSynthesis of fullerene on the surface of carbon nanoparticle by arc discharge method
Fullerenes materials have received wide attention due to their biomedical applications such as photodynamic therapy and magnetic resonance imaging [1]. The major limitations of realizing the practical applications of fullerenes are high cost and low production yield [2]. The arc discharge is well known technique for synthesis of carbon base materials. Here, we report the synthesis of fullerene ...
متن کاملFabrication, Purification and Characterization of Carbon Nanotubes: Arc-Discharge in Liquid Media (ADLM)
Carbon nanotubes (CNTs) were first discovered by Iijima in 1991 [1]. CNTs have sparked great interest in many scientific fields such as physics, chemistry, and electrical engineering [2, 3]. CNTs are composed of graphene sheets rolled into closed concentric cylinders with diameter of the order of nanometers and length of micrometers. CNTs are in two kinds, based on number of walls, the single-w...
