Title:
CARBON NANOTUBE AND METHOD FOR FABRICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/113993
Kind Code:
A1
Abstract:
Provided are a controllable-diameter carbon nanotube and a method for fabrication thereof. The method is: heating, in an inert atmosphere, a precursor obtained by reaction of a metal-organic framework, a metal salt, and an amino compound; performing carbonization; controlling the diameter of the carbon nanotube by means of changing the particle size of the metal-organic framework in the precursor. During the preparation process, the metal-organic framework with different particle sizes is obtained by means of simply changing the synthesis conditions such as solvent and reaction temperature, and thus the diameter of the carbon nanotube is controlled. The prepared carbon nanotubes have a bamboo-like morphology, and are doped in situ with a large amount of N. The method changes the electron structure of the surface of the carbon nanotube, further improving its electrochemical properties, and has great potential prospects for application in the field of energy conversion and storage.
