| 摘 要： | The deoiled asphalt as the carbon source and the ferrocene as the metal source and the catalyst precursor were chosen to synthe-size iron-containing carbon microparticles through co-carbonization at the temperature of about 450 ℃ for 3 h. The resulting products were treated at 2 000 ℃ for 2 h. All samples were examined by high resolution transmission electron microscopy (HRTEM) and X-ray diffraction (XRD). The results show that the iron particles in the heat-treated material are completely coated by carbon. In addition to the fully filled carbon microparticles as well as hollow carbon ones, also form carbon fibers with hollow centers. The formation mechanism of the as-prepared products was discussed briefly.
