Abstract

The invention relates to carbon nanotubes and, more particularly, the production thereof. The invention provides a method of preparing a catalyst for producing carbon nanotubes. The method includes, irradiating, with microwave radiation, a catalyst support supporting a metal compound, to form the catalyst. The invention also extends to a catalyst prepared according to a conventional method of preparing a catalyst for producing carbon nanotubes. The invention also provides a method of producing carbon nanotubes. The invention further provides use of the catalyst of the invention in producing carbon nanotubes.
