Abstract

Junk does the work: The observed heterogeneous electron-transfer (HET) rate of multiwalled carbon nanotube (MWCNT) materials is comparable to that of graphite only because CNT materials contain large quantities of nanographite impurities. When pure CNTs are used, the observed HET rate is actually significantly lower than that of graphitic materials. In other words, most of the electrochemical activity of CNTs is due to the presence of the nanographite impurities contained within them. (Figure Presented)
