SINGLE-WALLED CARBON NANOTUBE SYNTHESIS METHOD AND APPARATUS

摘要

Disclosed is a single-walled carbon nanotube synthesis method and apparatus, characterized in that a synthesis chamber of the carbon nanotube is divided into at least one first reaction chamber where a transition metal compound and hydrocarbon are fed and pyrolyzed, and a second reaction chamber where the pyrolyzed transition metal is dispersed, in which the second reaction chamber has a cross section wider than that of the at least one first reaction chamber, whereby the transition metal is rapidly dispersed from the first reaction chamber to the second reaction chamber. Thus, excessive growth of a catalytic transition metal due to re-combination of the transition metal is restrained, resulting in continuously preparing the single-walled carbon nanotube on a large scale.
