Effective separation of single-walled carbon nanotubes and their very different electrochemical behaviours†
Abstract
The electrochemical behaviors of m- and s-SWNTs obtained from as-prepared SWNTs using a novel binaphthyl based separation agent were studied. The s-SWNTs show higher capacitance but lower electrocatalytic activity, while m-SWNTs show the opposite. Their electrochemical properties can be further interconverted through changing the DOS by electron or hole doping.
