Abstract

In this paper, carbon mesospheres (CMs) with uniform shape were successfully synthesized by arc discharge method using Fe3O4 as catalytic material. Morphology of CMs was investigated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) technique. The obtained results showed that the synthesized CMs have an average diameter of 246 nm and were formed with different structures including solid structure and core-shell structure. Graphitic structure of CMs is characterized and confirmed by using both X-ray diffraction (XRD) and Raman spectroscopy. The prepared CMs with uniform size could be used for many potential applications for various industrial fields such as batteries, capacitors, fuel cells and especially in the commercial lubricants..
