High reaction activity of nitrogen-doped carbon nanotubes toward the electrooxidation of nitric oxide

Carbon nanotubes doped with N (NCNTs) enable 1.5 times faster electron-transfer kinetics for the oxidation of NO compared to pristine carbon nanotubes (CNTs), which may be due to the low adsorption energy for a NO on pyridinic NCNT(5,5) allowing NO to lose electrons readily and facilitate the following oxidation to nitrate.
