Abstract

Abstract: Carbon nanotubes were purified by use of electrical chemistry oxidation method. In the view of polarization curves it was discussed that electrochemistry method could be used in the purification of carbon nanotubus. The influence of current density, sulfuric acid concentration and reaction time on the reaction was studied, the optimum experimental condition was obtained and the mechanism of purification was also discussed.

Key words: Carbon nanotubes, Purification, Electrochemistry oxidation
