Xiamen University develops new technology for multi-walled carbon nanotubes

The transition metal nanocatalyst developed by the College of Chemistry and Chemical Engineering of Xiamen University was used to prepare new small and uniform multi-walled carbon nanotubes with a small diameter. At present, it has been granted 4 Chinese invention patents.

At present, the project has completed the expansion test of kilograms of multi-wall carbon nanotube preparation technology, and developed four kinds of carbon nanotube-promoted synthesis gas hydrogenation conversion to produce a new high-efficiency catalyst for low-carbon alcohols, and three types of carbon nanotubes promote carbon dioxide hydrogenation. Methanol efficient new catalyst.

The carbon nanotubes are suitable for battery electrode materials and high-efficiency capacitor materials, electrostatic shielding materials, reinforcing agents for new conductive polymer functional materials and performance modulation agents, catalyst carriers and accelerators, adsorption/ Desorption - separation media and the like. At present, "quasi-industrial" production facilities are under construction and it is expected that the production capacity can reach 50 tons of carbon nanotubes/year within 1 to 2 years.
