▎ 摘　　要

NOVELTY - Preparing carbon nanotubes by using graphene quantum dots as template, comprises (1) mixing 1,3,6-trinitropyrene with aqueous urea solution, and obtaining a graphene quantum dot solution modified with amino groups on surface by hydrothermal process; and (2) filtering solution through microporous membrane, dialyzing to pH=7.3, and freezing and drying at -20 degrees C to obtain the carbon nanotubes. USE - The carbon nanotubes is useful in fields of electrocatalysis, sensing, energy conversion and utilization. ADVANTAGE - The method: is simple and easy, can easily prepare on large scale. The carbon nanotubes: has highly controllable physical and chemical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for carbon nanotube is prepared by above mentioned method.
