Not all impurities are evil: We demonstrate here that the electrochemistry of single-walled carbon nanotubes (SWCNTs) and double-walled carbon nanotubes (DWCNTs) towards the reduction of azo groups is actually driven by the nanographite impurities within these CNTs. Put differently, most of the electrochemical activity of SWCNTs and DWCNTs towards the reduction of azo groups is due to the presence of the nanographite impurities contained within them.
