CNTs were synthesized over Fe2O3/MgO catalysts calcined at different temperatures by catalytic decomposition of methane at 1000°C. The synthesized CNTs were investigated by a combination of scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and Raman spectroscopy. The results show that the effect of calcination temperatures greatly governed the diameter and the quality of the SWCNTs formed. The catalysts calcined at 500, 600 and 700°C produced CNTswith the diameters of 1.53, 1.95 and 2.97nm, respectively. Generally, an increase in the calcination temperature increases the average diameter and decreases the quality of the CNTs produced. 2014-04-09T08:04:33Z 2014-04-09T08:04:33Z 2014 Article Advanced Materials Research, vol.832, 2014, pages 56-61 1662-8985 http://dspace.unimap.edu.my:80/dspace/handle/123456789/33566 http://www.scientific.net/AMR.832.56 10.4028/www.scientific.net/AMR.832.56 en Trans Tech Publications |
