Electrochemistry of carbon nanotubes

Abstract

The electrochemistry of carbon nanotubes is reviewed with the aim of summarizing what we can learn using these techniques, and what are the potential applications of nanotubes as electrode materials. Electrochemical charging changes the electronic structure. Consequently, electrochemistry and in-situ spectroelectrochemistry provide versatile tools for the investigation of fundamental effects related to the electronic structure of carbon nanotubes. This approach is compatible with chemical doping, but the electrochemical charging of nanotubes allows for precise control of the doping conditions. Salient (spectro)electrochemical data accumulated during the last ten years on SWNTs, DWNTs and fullerene peapods are here reviewed.
