摘要：

A cost-effective approach to prepare carbon spheres (CSs) in a large quantity by pyrolizing the C2Cl4/Fe(C5H 5)2 mixture at 550°C, was discussed. The mixture was loaded into a stain-less steel autoclave and put into an electronic furnace at a constant temperature of 550°C. The dark solid formed after a period of cooling down at room temperature, was divided in to two parts. These products were then analyzed through x-ray powder diffraction (XRD), raman spectrum and field emission scanning electron microscopy (FSEM). FSEM and transmission electron microscopic (TEM) images revealed a large quantities of carbon spheres of the range 30-580 nm sizes.
