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

Abstract:

Article Preview

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.
