The Carbon Nanotubes with Different Chemical Treatments and Their Electrochemical Voltammetric Reponses

Article Preview

Abstract:

The carbon nanotubes with carboxyl groups were obtained by using different chemical treatment methods. The electrical properties of the carbon nanotube films were investigated and voltammetric responses for Fe3+ / Fe2+ were measured at the carbon nanotube film electrodes.
