熔盐法制备石墨化碳纳米片
Synthesis of Graphitized Carbon Nanosheet by Molten Salt Method
摘 要
以二氨基马来腈为原料、氯化铁为催化剂前驱体、ZnCl2-KCl为熔盐介质，采用熔盐法制备石墨化碳纳米片，研究了反应温度和熔盐/反应物质量比（盐料比）对产物物相组成、显微结构和石墨化程度的影响。结果表明：随着反应温度的升高和盐料比的增加，产物的石墨化程度增大，片状结构的占比增大；当反应温度为1 000 ℃、盐料比为40∶1时，制备得到了石墨化碳纳米片，其直径为2~10 μm，厚度为30 nm。

Abstract
Graphitized carbon nanosheets were prepared by molten salt method with diaminomaleonitrile as raw material, iron trichloride as catalyst precursor, and ZnCl2-KCl as molten salt medium. The effects of reaction temperature and salt to reactant mass ratio on the phase composition, microstructure and degree of graphitization of the product were investigated. The results show that the degree of graphitization and the proportion of flake structure in the product increased with the increase of reaction temperature and salt to reactant mass ratio. When the reaction temperature was 1 000℃ and the salt to reactant mass ratio was 40:1, the graphitized carbon nanosheets with diameter of 2-10 μm and thickness of 30 nm were obtained.
