Synthesis of carbon nanotubes by Arc-discharge in liquid: a novel double wall beaker set-up

Carbon nanotubes (CNTs) represent an important group of nanomaterials with attractive geometrical, electrical and chemical properties and are synthesized using a variety of techniques. CNTs have been extensively studied in our previous works and in this study were fabricated by arc discharge full automatic set up in liquid and in double wall beaker which does not require vacuum equipment, heat exchange system, active or inert gases. This technique was full automatic which enabled the controlling of gap between the two electrodes. Carbon nanotubes were fabricated between two graphite electrodes which were submerged in the LiCl(0/25N) and with a voltage of 20-30v while using Ni as a catalyst. The scanning electron microscopy (SEM) and TEM was employed to study the morphology of these carbon nanostructures.
