摘要：
In this paper a great deal of carbon microspheres with high purity, uniform diameter and good features were synthesized by CVD method, while acetylene and toluene were used as carbon sources. The obtained carbon microspheres were almost amorphous. The products were treated by microwave plasma and temperature vacuum heat treatments respectively, then the samples were analyzed and characterized by FESEM, XRD and HRTENL The results showed that carbon microspheres were well graphitized while their features were undestroyed. Based on their adsorption isotherms of nitrogen, pore structures of carbon spheres were found to be changed greatly after graphitized treatments. (c) 2006 Elsevier B.V. All rights reserved.
