Non-carbon nanotubes are important members of the quasi-one-dimensional nanomaterial family. Among many kinds of non-carbon nanotubes, the non-carbon nanotubes prepared from nitrides have excellent physical and chemical properties and have attracted more and more attention. Due to the large specific surface, nitrides nanotubes exhibit high chemical activity and unique physical properties. In addition, new functional properties of nitride nanotubes can be obtained through physical or chemical modification, which can greatly broaden their applications.
- Boron nitride nanotubes: Boron nitride nanotubes have superior physical and chemical properties, and one outstanding property is the strong stability. In particular, boron nitride does not react with various liquid substances in living organisms, so it can be used as a key material for nano-biological components and has a wide range of application prospects. Boron nitride nanotubes can be obtained by various methods, such as arc discharge, chemical vapor deposition, laser ablation, carbon thermal reduction, carbon nanotube template, high temperature decomposition, ball grinding, and hydrothermal synthesis.
- Aluminum nitride nanotubes: Aluminum nitride nanotube is an important electronic optical material, which has good thermal conductivity, high dielectric constant, wide band gap and the others. Aluminum nitride nanotubes are promising materials for fluorescence, display and lighting applications.
- The others: There are other kinds of nitride nanotube, such as GaN nanotube, CNx,(BN)xCy nanotube and the others. For GaN nanotubes, the synthesis of GaN nanotubes generally requires a template. In addition, compared with GaN powder, the GaN nanotube has a wider band gap.
