Nitrogen doped carbon nanotubes are a new type of nanomaterial with excellent physical and chemical properties, and have broad application prospects.
First, nitrogen doped carbon nanotubes can be prepared by various methods, such as chemical vapor deposition, chemical vapor deposition arc discharge, electrochemical oxidation and reduction, sol gel method, etc. Among them, nitrogen doped carbon nanotubes prepared by chemical vapor deposition method have the characteristics of uniform size and complete lattice structure.
Secondly, the properties of nitrogen doped carbon nanotubes are also very excellent. Due to the doping of nitrogen atoms, the electronic structure of carbon nanotubes is altered, resulting in nitrogen doped carbon nanotubes having superior electrocatalytic activity, electrochemical performance, photocatalytic performance, conductivity, mechanical strength, and other properties compared to pure carbon nanotubes. Therefore, nitrogen doped carbon nanotubes can be widely used in energy conversion, catalytic reactions, electronic devices, biomedical and other fields.
Finally, the application prospects of nitrogen doped carbon nanotubes are very broad. In terms of energy conversion, nitrogen doped carbon nanotubes can be used as photocatalytic materials to prepare efficient solar cells and water decomposition catalysts, and as electrocatalytic materials to prepare high-performance fuel cells and electrochemical supercapacitors. In terms of catalytic reactions, nitrogen doped carbon nanotubes can be used as catalysts for efficient organic synthesis and environmental governance. In terms of electronic devices, nitrogen doped carbon nanotubes can be used as high-performance conductive materials for the preparation of flexible electronic devices. In biomedicine, nitrogen doped carbon nanotubes can be used as nano drug carriers, photothermal therapeutic agents, and molecular imaging probes for cancer treatment and molecular diagnosis.
