Abstract
I n this work the effects of MgO-supported iron oxide nanoparticles size on CNTs dimensions; synthesized by CCVD method has been investigated. The supported iron oxide nanoparticles are produced by impregnation method. Fe(NO 3 ) 3 . 9H 2 O salt and MgO powder were used as precursor materials for Fe and MgO, respectively. In order to provide different size nanoparticles, loading ratio of Fe to MgO in samples was varied through 15%-85%, 25%-75%, 35%-65%, and 45%-55%. Carbon nanotubes are synthesized using prepared support as catalytic substrate employing CCVD method. Acetylene and Argon gases are used as carbon source and carrier/cleaner gas, respectively. According to our results, with increasing the loading mass ratio of Fe to MgO, the catalyst nanoparticles size is increased as a result of which the diameter of synthesized CNTs increases.
