Carbon nanotubes -based electrochemical structure

Without doubt, the advent of carbon nanotubes has opened up iimovative perspectives for research and development of carbon electrodes. In this chapter, we have attempted to highlight the electrochemical properties of carbon nanotubes by rooting them mainly on their structural, electronic and chemical properties. If chirality of SWNTs could be controlled, it would be possible to probe electrochemically the unique electronic properties of the tubes with their corresponding unique DOS distribution and establish direct correlations between electronic structure and electrochemistry. However, so far, most of their electrochemical applications are based on ensembles of CNTs (MWNTs or SWNTs) in thin films supported on conductive surfaces or composites. Such ensembles, not so well defined from the structural point of view, contain a mixture of tubes with different diameters and DOS...

Chun et al. [93] produced carbon nano fibers with diameter in the range from 100 nm to a few microns from electrospim polyacrylonitrile and me-sophase pitch precursor fibers. Wang et al. [94, 95] produced carbon nanofibers from carbonizing of electrospun PAN nanofibers and studied their structure and conductivity. Hou et al. [96] reported a method to use the carbonized electrospun PAN nanofibers as substrates for the formation of multiwall carbon Nanotubes. Kim et al. [14, 97] produced carbon nanofibers from PAN-based or pitch-based electrospim fibers and studied the electrochemical properties of carbon nanofibers web as an electrode for supercapacitor.
