采用乙醇为碳源,乙酸钴为催化剂,通过简易的溶剂热“一锅法”,在600℃下制备了石墨化炭空心材料( GHS).借助X射线衍射仪(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)和拉曼光谱法(Raman)对产物的结构和形貌进行了表征.结果表明:材料具有较高的石墨化程度,并呈现明显的中空结构.

Graphitic carbon with a hollow structure (GHS) was hydrothermally prepared at 600 ℃ by a one-pot method by the pyrolysis of ethanol,with cobalt acetate as catalyst.The characteristics of the samples were investigated by X-ray diffraction,scanning and transmission electron microscropy and Raman spectroscopy.Results show that as-synthesized samples had hollow structures with high graphitization degree.A possible mechanism for GHS formation by the method is proposed.
