Abstract

Unprecedented open ended nitrogen doped carbon nanotubes prepared by direct pyrolysis of [Co(HTTG)(H₂O)₂]_n (TTG= N,N′,N′′-1,3,5-triazine-2,4,6-triyltris-glycine) show among the largest surface area of multiwalled nanotubes and high CO₂/CH₄ adsorption selectivity which increases with increasing of nitrogen content.
