Nitrogen, boron and phosphorus and carbon atoms similar size, there may be inserted into the graphite structure, thereby altering the chemical, mechanical and electrical properties of carbon nanotubes. In particular, nitrogen-doped carbon nanotubes having n-type doping, the electron density changes around a nitrogen atom, it has a good electron conductivity, which are also aspects of the electronic effect of the catalytic material exhibits unique properties.

Nitrogen doping methods: nitrogen atoms in the carbon nanotubes doped with built-in, replace the formula and graft type, and so, we are using the graft type. Grafting reaction in the formula is a nitrogen-containing walls of carbon nanotubes modified by a chemical group, such as a nitrogen group, amino acid group and the like.

Preparation: chemical vapor deposition method. Chemical vapor deposition produced nitrogen-doped mass fraction is relatively low, usually around 3.5%. Difficult to achieve even higher levels.

The nitrogen-doped carbon nanotubes as catalyst supports in direct catalytic and catalytic, super capacitors and power of heterogeneous catalysis to extensive research, especially showing good performance when used as a catalyst carrier. Nitrogen surface of carbon nanotubes can improve the dispersion of metal nanoparticles and enhanced carrier interaction with the active site.
