Preparation process of a supported catalyst for producing carbon nanotubes

摘要

Synthesis of a catalyst (I) for the manufacture of multi-wall and nanotubes comprises mixing aluminum hydroxide powder (Ia) (80 mu m) with an aqueous iron (Ib) and cobalt salt solution (Ic) to form a paste, drying the paste to a powder with a water content (which is lower than 5 wt.%) and selecting a particle shape lower than 70 mu m.
