Synthesis of carbon nanotubes from acetylene on the FeCoMgO catalytic system obtained by ball milling

Highly crystalline multi wall carbon nanotubes have been synthesized by RF-CVD from acetylene at 850°C over a Fe:Co:MgO catalyst. The catalytic system was obtained by mixing for 100 h Fe, Co and MgO powders in a ball milling device under petroleum ether environment, followed by oxidation in air at 5...

Description
Summary:Highly crystalline multi wall carbon nanotubes have been synthesized by RF-CVD from acetylene at 850°C over a Fe:Co:MgO catalyst. The catalytic system was obtained by mixing for 100 h Fe, Co and MgO powders in a ball milling device under petroleum ether environment, followed by oxidation in air at 500°C for 24 h. Most of the nanotubes had external diameters in order of dozens of nm and lengths of microns, resulting in an aspect ration of over 1000. Their external to internal diameter ratio varied between 2.5 and 3.
