Abstract

The invention discloses a method for preparing a carbon nanotube by coal, which comprises the steps of mixing powdered coal with water, melamine and soluble cobalt salt or nickel salt, carrying out wet milling by utilizing high-energy ball milling to obtain a slurry mixture, and carrying out freeze drying on the mixture to obtain a porous block. The block is placed in a high-temperature atmosphere furnace and sintered in a hydrogen/argon mixed atmosphere to prepare the cluster-shaped carbon nano-tube, and finally, the relatively pure carbon nano-tube is obtained through acid washing and water washing. The invention uses natural coal as raw material, does not need to pretreat the coal, has low selectivity to the coal types and high yield, and the prepared carbon nanotube has the diameter of 40-100 nanometers and uniform distribution of the diameter of the carbon nanotube; and the preparation process is simple, the process is simplified, the equipment requirement is low, the cost is low, and the industrial production is easy to realize. Has huge market demand and wide application prospect in the fields of lithium ion batteries, supercapacitors, nano catalysis, biomedicine, environmental protection and the like.
