Catalytic production of carbon nanotubes by fluidized-bed CVD

The large scale production of carbon nanotubes (CNTs) is a major issue for their use in industry. Among the different techniques used for their synthesis, catalytic (C)CVD in fluidized-bed reactors appears one of the most promising. In this article we present the current state of this new technology and we aim to highlight its great flexibility through examples which depict the selective preparation of different kinds of carbon nanomaterials from different catalysts. Finally, we present the results of scale-up experiments that permit an increase in carbon nanotube production by two orders of magnitude.
