WebbProduction Methods. Carbon nanotubes can be synthesized using different methods. Amongst the most common arc discharge [1-5], laser ablation [6], chemical vapor deposition (CVD) from hydrocarbons [7-11] and high pressure conversion of carbon monoxide (HiPco) [12]. The production of CNTs with high purity and uniformity, low … Webb(AD-SWNT) and HiPco SWNT (H-SWNT). The arc-discharge method in principle is based on an electric arc generated between two graphite electrodes under an inert atmosphere of helium or argon. Two graphite rods are used as electrodes. A current is passed through the electrodes and plasma is created between them.
