Experimental Study on Catalytic Effect of Iron Compounds During Synthesis of Carbon Nanostructures From Coal

摘要

Carbon nanofibers (CNFs) and carbon nanorods (CNRs) are synthesized using coal particles (44micron) as carbon source in the presence of Ferrocene and Fe3O4 nanoparticles (50-70nm) as catalysts in solid phase at 800°C. Additionally the catalytic effect of Fe2(SO4)3.xH2O on the coal particles was studied. The as-synthesized samples have been characterized through scanning electron microscopy (SEM), field emission scanning electron microscopy (FESEM), transition electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDX) and X- Ray Diffraction (XRD). The results revealed amorphous carbon nanostructures such as: CNFs and CNRs are formed. The diameter of CNFs and CNRs are in the range of 30-40 nm and 60-80nm respectively. The effect of solid catalysts on the formation of carbon nanostructures described here.
