Electrochemical Oxidations of p-Doped Semiconducting Single-Walled Carbon Nanotubes

摘要

Two oxidation peaks at 0.99, 1.48 V versus Fc/Fc~+ appear in the cyclic voltammograms of a series of defect-site functionalized SWNTs in methylene chloride solution in the presence of ferrocenes. These two peaks are demonstrated to be the electrochemical responses to the independent oxidation of v_1 and v_2 valence bands of p-doped semiconducting SWNTs.
