摘要
对CoCl2-FeCl3-膨胀石墨层间化合物(EGICs)的制备进行了探讨。结果表明保持其它制备条件不变,仅改变膨胀石墨(EG)与FeCl3的配比即可合成不同阶结构的EGICs;随着n(EG)∶n(FeCl3)增大,EGICs趋向于高阶,在一定配比下可合成纯阶样品;原料配比固定,提高反应体系的Cl2分压有利于制得纯净的EGICs。
In this paper, the synthesis process of CoCl2-FeCl3-exfoliate graphite intercalation compounds （CoCl2-FeCl3-EGICs） is studied. The results indicate that the molar ratio of EG to FeCl3 lays an important role in the stage structure of EGICs： as the ratio of EG to FeCl3 increases,the stage number increases. Under an appropriate molar ratio of EG to FeCl3, pure-stage EGICs can be got. When the reactant ratio is determined, increasing the partial pressure of Cl2 in reaction system is of advantage to gain pure：stage EGICs.
