The structure of defects in nanotubes, which occur spontaneously or can be created by doping, has also been extensively studied (44-46). In particular, several teams used EELS to probe the chemical bondings of nitrogen in nitrogen doped carbon nanotubes (47,48).

Doping carbon nanotubes with nitrogen atoms at lower concentrations than 6.5 wt% induce crystalline disorder in the graphene sheets, as well as an excess of electron donors on the nitrogen-rich areas may result in a more reactive structure compared to pure carbon nanotubes.

Recently, the research on exploring the use of carbon nanomaterials as metal-free catalysts has been one of the major subjects for the fuel cell research. Owing to their wide availability, environmental acceptability, corrosion resistance, and unique surface and bulk properties, carbon nanomaterials are ideal candidates for metal-free ORR catalysts. In this context, we have demonstrated that vertically aligned nitrogen-doped carbon nanotube (VA-NCNTs) array exhibited three times higher ORR electrocatalytic activity and better long-term operation durability...

It has also been seen that two nanomaterials can be functionalized with each other. One example is the synthesis of fullerene (C6o)-functionalized GNPs by the coupling of the fullerene molecules with peripheral amine moieties on the particle surface [66]. On the other hand, GNPs were selectively attached to chemically functionalized surface sites on nitrogen-doped carbon nanotubes. A cationic polyelectrolyte was adsorbed on the surface of the nanotubes by electrostatic interaction between carboxyl groups on the chemically oxidized nanotube surface and polyelectrolyte chains.
