| 摘 要： | 研究了二茂铁和氯化铵的用量对气压法制备炭空心球直径的影响.炭空心球的形貌与直径通过场发射扫描电镜表征.实验发现:炭空心球的直径主要分布在1 μm ～10 μm,形貌基本一致.在二茂铁与氯化铵质量比一定时,炭空心球的直径随着原料总量增加而增大.当氯化铵过量时,炭空心球的直径存在双峰分布,但中位径基本不变.在合成过程中,铁颗粒与液态Fe(NH3)2Cl2模板的团聚,以及铁铵络合物之间的相互转化是影响炭空心球直径的主要因素.

| Abstract: | The effects of the amount of the ferrocene and ammonium chloride on the diameter distribution of hollow carbon spheres (HCSs) prepared in high-pressure argon were investigated. The morphology and diameter distribution of the HCSs were characterized by field-emission scanning electron microscopy which showed that the diameter of most HCSs ranges from 1 to 10 μm. The median diameter increases with the total amount of the reactants with the same weight ratio of ferrocene to ammonium chloride. When excess ammonium chloride is used, HCSs with a bimodal diameter distribution are prepared; however, the median diameter is almost the same. It is proposed that the aggregation of iron particles and liquid Fe(NH3)2Cl2 templates, and the transformation of the iron amine complexes, in the process mainly influence the diameter distribution of the HCSs. |
