4DescriptionAbstract Carbon nanomaterials were synthesized from Al2O3, CaCO3 and MgO used as support materials without a catalyst and over Mo/Fe catalyst on Al2O3, CaCO3 and MgO as support materials. The as-prepared nanomaterials were characterized by Raman spectroscopy, Thermogravimetric and Derivative thermogravimetric analysis (TGA & DTA). The intensity ratios (ID/IG), of the D- and G-bands were higher for Al2O3, CaCO3 and MgO as support materials and lower for Mo/Fe/Al2O3, Mo/Fe/CaCO3 and Mo/Fe/MgO. The ratios of the sp2/sp3 bonded carbon were lower in the support than in the catalyst and support. TGA and DTA curves show MgO and Mo/Fe/Al2O3 lost 37.39% and 11% mass respectively while Mo/Fe/CaCO3 and Mo/Fe/MgO barely decomposed under high temperatures.
