Structure and preparation of N-doped carbon nanotubes and its catalytic application

The doping of nitrogen atoms in carbon nanotubes increase the basicity of carbon nanotubes, and then surface adsorption properties of carbon nanotubes are changed. The high electron density of nitrogen atoms doped in carbon nanotubes results in the unique properties of carbon nanotubes in electronics, materials and catalysis. In this paper, the structure characteristics, preparation methods and application of carbon nanotubes in catalysis were review.
