Electrochemical Characterization of Catalytic Activities of C60 Nanowhiskers to Oxygen Reduction in Aqueous Solution

Abstract

We have investigated the catalytic function and activity of C60 nanowhiskers (C60NWs) on glassy carbon electrodes to the electrochemical O2 reduction in aqueous solution by cyclic voltammetry. It is found that C60NWs are active catalysts for O2 reduction in aqueous solution, although pristine C60 powders do not show any activities. The porous and conductive features of C60NWs play important roles in the electrochemical O2 reduction.
