Description

Technical Field

[0002] Carbon nanomaterials generally include carbon black, carbon nanotubes, mesoporous carbon, carbon aerogels, etc. Carbon nanotubes, also known as buckytubes, are one-dimensional quantum materials with a special structure (radial size is in the nanometer range, axial size is in the micrometer range, and both ends of the tube are basically sealed).

[0003] There is an existing device for preparing carbon nanocarriers (application number: 202322170531.2). By placing a quartz tube into a high-temperature furnace body, and then focusing a laser beam on a graphite target in the quartz tube through a laser light source, the operation of generating gaseous carbon under laser irradiation can achieve the effect of facilitating laser evaporation preparation of carbon nanocarriers, simplifying the operation steps, and improving the preparation efficiency. The above still exists. When preparing carbon nanocarriers, it is necessary to place the preparation material (metal catalyst / graphite mixed graphite target) in the quartz tube, heat the furnace body, and when the furnace temperature rises to a certain temperature, flush the inert gas into the tube, and then start the laser light source through the console. The laser The light source focuses a laser beam on the graphite target in the quartz tube, and generates gaseous carbon under the irradiation of the laser. When these gaseous carbon and catalyst particles are carried from the high-temperature zone to the low-temperature zone by the airflow, they grow into CNTs under the action of the catalyst. By changing the growth temperature, catalyst components and other conditions, the average diameter and diameter distribution can be changed, thereby completing the production and preparation work. However, due to the different amounts of preparation materials placed in the quartz tube, the heights of the preparation materials piled up in the quartz tube are also different, and the position of the laser light source is always fixed, which may lead to the situation where it cannot be irradiated, making it inconvenient for the staff to adjust the position of the laser light source, and thus making it inconvenient to prepare different amounts of carbon nanocarriers.
