  • Method of synthesising a support catalyst for the production of carbon nanotubes
    Patent number: 7754181
    Abstract: The present invention relates to a method for synthesising a catalyst with a view to the production of multi-wall nanotubes comprising the following stages: mixing an Al(OH)3 powder having a particle size lower than 80 ?m with an aqueous solution of an iron and cobalt salt, the whole forming a paste; drying said paste until a powder with a moisture level lower than 5% by weight is obtained; selecting the particle-size fraction that is lower than 70 ?m.
