Discharge Characteristics on the Synthesis of Carbon Nanostructures through Arc-Plasma in Water

Simple arc discharge technique was used for formation of carbon nonmaterials without using any type of gases. The used arc discharge technique between the pure graphite electrodes with different diameters for anode submerged in water at room temperature. Arc plasma is produced using D.C power supply with current (3090amp), and voltage (5-25volt).The discharge characteristics of the arc plasma generation in water and, with Ni catalyst and in NaCl solution were examined with the change in working parameters of electrode diameters and related arc current. The nanostructures obtained of these experiments were examined by scanning electron microscope (SEM).
