METHOD FOR THE SELECTIVE PRODUCTION OF ORDERED CARBON NANOTUBES IN A FLUIDISED BED.

摘要

The invention relates to a method for the selective production of ordered carbon nanotubes by decomposition of a carbon source in the gaseous state in contact with at least one solid catalyst, said catalyst taking the form of metallic particles borne by carrier grains. The catalyst grains are adapted so as to be able to form a fluidised bed containing between 1 % and 5 % by weight of metallic particles having average dimensions of between 1nm and 10nm. The decomposition takes place in a fluidised bed of catalyst grains. The invention can be used to obtain pure nanotubes with predetermined dimensions in a high yield.
