Description

technical field [0001] The invention relates to a chemical reaction method, in particular to a method for preparing carbon nanotubes using cobalt chloride as a catalyst and glucose as a raw material. Background technique [0002] Carbon nanomaterials are widely used in various technological and energy-related fields due to their excellent electronic properties and mechanical stability. In particular, carbon nanotubes are hailed as a rapidly rising star material due to the advantages that they can be regarded as rolled from graphitic carbon layers, have a one-dimensional lumen structure, and have lumen sizes ranging from one to several hundred nanometers, Therefore, it can be used as a nanoreactor or filled with other nanomaterials into the lumen to synthesize nanocomposites with novel properties, making it widely used in fuel cells, biological probes and chemical catalysis. [0003] Generally, the preparation methods of carbon nanotubes mainly include arc discharge method, ...
