Embodiment 1

[0022] Preparation of organic montmorillonite by ion exchange reaction. First, in 1000 mL of 80 °C deionized water, 1 mole of octadecylamine was acidified with equimolar concentrated hydrochloric acid, then injected into 1500 mL of montmorillonite dispersion, and continued to mix mechanically for 30 minutes. The obtained white precipitate was filtered and washed with 80 °C Washed with deionized water for 3 times, then air-dried naturally, and pulverized the organic montmorillonite with a pulverizer; finally, dried in a vacuum oven at 60°C for 24 hours.

[0023] With the alumina-silicon oxide hybrid with a particle size of 10 microns as the carrier, the nickel nitrate aqueous solution and the alumina-silicon dioxide hybrid were mixed at 40 °C in a weight ratio of 40 nickel: 60 alumina-silicon hybrid Mix under stirring for 1 hour. The obtained product was put into a muffle furnace and dried at 100° C. for 8 hours. Then calcined at 400°C for 3 hours, and finally used argon cont...

Description

technical field [0001] The invention relates to a method for synthesizing a carbon nanotube material, in particular, the invention relates to a method for synthesizing a carbon nanotube through a combustion method by using a polyolefin-montmorillonite composite material under the action of a loaded catalyst. technical background [0002] It is already known that, from a microscopic point of view, carbon nanotubes are formed like this: a carbon atom combines with three adjacent carbon atoms to form a hexagonal ring between the carbon atoms, which is composed of honeycomb and repeated hexagonal rings When unfolded in a plane, it forms a cylindrical shape. Carbon nanotubes are characterized by diameters ranging from several angstroms to tens of nanometers, and aspect ratios ranging from tens to thousands. Carbon nanotubes have been widely used due to their excellent physical and mechanical properties and electrical conductivity. In recent years, there have been more and more ...
