Résumé / Abstract
Carbon nanotubes were synthesized by CCVD with inductive heating from acetylene on a Fe-Co/CaO catalyst obtained from the thermal decomposition of the Fe:Co:CaCO3
catalyst in nitrogen, previous to the growth process. MWCNTs were synthesized at 750, 850 and 950 °C and characterized by TEM, TGA and Raman Spectroscopy. The nanotubes presented a ratio of the outer to inner diameters between 2 to 3, and 90 % of all them have diameter values ranging from 5-25 nm, with an aspect ratio in the order of hundreds. As the reaction temperature increased, the synthesis efficiencies decreased and the amount of metallic nanoparticles encapsulated inside the nanotubes increased.
