Abstract Submitted to the    NANOTUBE'04 Conference:

Carbon nanotubes were synthesis by chemical vapor deposition synthesis of methane on Co-Mo/MgO nanoporous MgO, that synthesis by sol-gel method. Large quantities of nanotubes can be produced by this technique due to the high specific surface area (210 m2/g) of nanoporous MgO. The main advantage of MgO is its high solubility in hydrochloric acid. Different synthesis parameters such as the Co-Mo content in the catalyst (2–10%), the synthesis temperature (800–1000 ^oC) and the synthesis time (5-40 min.) were investigated. TEM, SEM, TGA, X-ray diffraction, Raman spectroscopy and BET characterized the synthesized material. The best experimental condition could result in carbon nanotube yield and high quality. Purified samples consist of high yield of carbon nanotube (100%) and more than 60% SWNTs.
