Abstract
Disclosed are methods for decapping single wall carbon nanotubes and purifying the decapped single wall carbon nanotubes. The disclosed methods include the steps of oxidizing the single wall carbon nanotubes to remove the terminal end cap and subsequently acid washing the single wall carbon nanotubes to remove the catalyst particles. The resulting carbon nanotubes have improved BET surface area and pore volume.
