Title:
PRODUCTION METHOD FOR CARBON NANOTUBES
Document Type and Number:
WIPO Patent Application WO/2023/190783
Kind Code:
A1
Abstract:
Provided is a new method capable of highly efficiently producing high-purity monolayer carbon nanotubes without the fear of a reduction in the strength of a reaction tube. This production method for carbon nanotubes by floating catalyst chemical vapor deposition (FC-CVD) comprises: a step for heating a raw material for carbon nanotubes in the presence of an iron-containing catalyst and an alkali metal compound to generate carbon nanotubes.
