Abstract

A method of growing carbon nanotubes includes following steps. A reactor is constructed, wherein the reactor includes a reactor chamber and a rotating mechanism inside the reactor chamber. A carbon nanotube catalyst composite layer is applied, the carbon nanotube catalyst composite layer is configured to be rotated by the rotating mechanism in the reactor chamber, and the carbon nanotube catalyst composite layer includes a carbon nanotube layer and a number of catalyst particles dispersed in the carbon nanotube layer. The carbon nanotube catalyst composited layer is positioned inside the reactor chamber. A mixture of carbon source gas and carrier gas is introduced into the reactor chamber. The carbon nanotube catalyst composite layer is rotated. The carbon nanotube catalyst composite layer is heated to grow carbon nanotubes.
