Abstract

The invention discloses a method for preparing a vermiculite carbon nanotube composite material by a vertical microwave reactor. The method comprises the following steps: adding expanded vermiculite into the vertical microwave reactor, tangentially introducing inert gases as carrier gases, performing microwave heating, introducing reaction gas and a catalyst into the vertical microwave reactor after reaching the reaction temperature, and carrying out a catalytic reaction, thereby obtaining the vermiculite carbon nanotube composite material. According to the method disclosed by the invention, by virtue of microwave heating, the heating rate is rapid and effective. Meanwhile, due to the vertical microwave reactor, the gases are discharged, and gas suck-back is avoided. The prepared vermiculite carbon nanotube composite material is high in purity, uniform in morphology and excellent in monodispersity, and has large specific surface area, and the synthetic method is simple, effective and uniform in gas distribution, the energy consumption is low, the equipment is simple, the production efficiency is improved, the amount of pollutants is small, and the method has high economic value.

Description

technical field [0001] The invention relates to the preparation of a vermiculite carbon nanotube composite material, in particular to a method for preparing a vermiculite carbon nanotube composite material with a vertical microwave reactor. Background technique [0002] Tube furnaces are mainly used in metallurgy, glass, heat treatment, lithium battery positive and negative materials, new energy, abrasive tools and other industries, and are professional equipment for measuring materials under certain temperature conditions. The furnace structure is simple, easy to operate, easy to control, and capable of continuous production, but the temperature rises slowly, the reaction cycle is long, and the reaction process is not easy to control. It needs to be improved to increase efficiency. [0003] CNTs (carbon nanotubes) are considered to be the most versatile nanofunctional materials. In various fields, as an important platform material, CNTs have attracted the attention of many...
