Cyclic Voltammetry of Carbon Nanotubes Prepared by Arc Discharge Method

Abstract

In this research, A developed method was used to prepare carbon nanotubes from the graphite
rods Extracted from used batteries. An electric discharge method was used between two
carbon electrodes in deionized water, one representing the anode and the other the cathode.
The cathode contains catalysts such as copper. Three different battery models (80 -100 - 120)
ampere, have been prepared, where a precipitate resembling a sponge was obtained in
deionized water, and after filtration, the carbon nanotubes was obtained. Several techniques
such as Field Emission Scanning Electron Microscopy (FESEM), Transmission Electron
Microscopy (TEM), and X-ray Diffraction (XRD) were used to detect the resulting carbon
nanotubes, whereby carbon nanotubes were obtained. With a diameter ranging from (4) to
(11) nanometers and a length from (120) to (1182) nanometers. In the present study, a new
method was used to determine the electric current, and potential difference, of carbon
nanotubes in electrolyte using an electrochemical method (cyclic voltammetry) for sample
M1, M2, and M3 prepared by electric arc discharge, These results indicate that M1 samples
(a carbon nanotubes prepared from arc discharge system for sample 80A) are more reactive
than M0, meanwhile, M3 shows slightly better redox property than M2 and M1. M1, M2, and
M3 all show the ability to act as battery cells.
