Abstract

The invention relates to a synthesis method of a crystal whisker-shaped carbon nanotube. The synthesis method is characterized by comprising the following steps: (1) dissolving ferrocene into benzene solution according to a weight volume ratio of 1: (10-50) and filtering; and (2) injecting the prepared ferrocene-benzene solution into a synthesis furnace by using an atomizer through mixed gas of hydrogen and nitrogen, wherein the temperature of the synthesis furnace is controlled to be 900 to 1,200 DEG C. The synthesis method is simple, wide in sources of raw materials and applicable to large-scale production.

Description
