Abstract
An embodiment of the present specification provides a method for preparing a carbon nanotube, comprising: (a) introducing a catalyst into a chemical vapor deposition reactor; and (b) injecting a carbon source gas to synthesize a carbon nanotube, wherein an input of the catalyst and a flow rate of the carbon source gas satisfy the following Formula 1: 0.1 L/g·min≤a/b≤1.1 L/g·min [Formula 1] wherein a represents a flow rate (L/min) of the carbon source gas and b represents an input (g) of the catalyst.
