1. What are ultra-high purity double-walled carbon nanotubes?

Double-walled carbon nanotubes are a type of nanomaterial consisting of two concentric carbon nanotube shells. The diameter of each carbon nanotube is usually between 1 and 100 nanometers, and the wall thickness is often only a few atoms thick.

2. Structure of double-walled carbon nanotubes

Double-walled carbon nanotubes usually consist of two concentric carbon nanotube shells. The diameter of the inner tube is 0.7 to 1.5 nanometers, and the diameter of the outer tube is 1.0 to 2.0 nanometers. There is usually a gap of 1 to 3 lattice spacings between the two tube layers, called the "gap layer".

3. Application of ultra-high purity double-walled carbon nanotubes

Double-walled carbon nanotubes have many unique physical and chemical properties, so they have broad application prospects in many fields, including the following aspects:

1. Hydrogen storage materials

The structure of double-walled carbon nanotubes can improve the adsorption and retention capacity of hydrogen, so they are very suitable as hydrogen storage materials.

2. Battery materials

Due to the excellent conductivity of double-walled carbon nanotubes, they can be used in electronic devices such as batteries and supercapacitors.

3. Catalyst carrier

The structure of double-walled carbon nanotubes can be used to prepare catalysts with good stability and high activity.

4. Biomedical applications

Double-walled carbon nanotubes have unique optical and fluorescence properties, which make them have broad application prospects in the biomedical field.

In short, as a new type of nanomaterial, ultra-high purity double-walled carbon nanotubes have broad application prospects. With the continuous development of science and technology, it will show its great potential in many fields.
