Production of Multiwalled Carbon Nanotubes Using the Aerosol Method

A new synthesis method has been invented for the production of carbon nanotubes. We have called this method the aerosol method since the fundamental synthesis routine is to create aerosols of organic solvent and metal particles by atomising a solution of a metal salt in a solvent using pure hydrogen gas. This method enables us to easily control the size of the catalyst particles. Reactions have been carried out at 700°C and 1000°C and in both cases multi‐walled carbon nanotubes have been produced. The tubes are characterised using scanning and transmission electron microscopy, and X‐ray diffraction.
