石墨结构层包嵌铁纳米粒子是一种纳米尺度复合材料,具有类似三明治的结构.研究表明,其拉曼光谱的E2g2模出现了红移,说明铁纳米粒子外部原子将部分电荷转移给了碳网,与其X射线光电子能谱的分析结果吻合.2阶和3阶石墨层间化合物前驱体的拉曼光谱与其它受主型石墨层间化合物的类似,其内部层碳网和边界层碳网的E2g2模频率不同. Graphite layer embedded iron nanoparticles is a nanoscale composite with a sandwich-like structure. Studies have shown that the E2g2 mode of Raman spectroscopy shows a red shift, indicating that the external atoms of iron nanoparticles transfer part of the charge to the carbon The results of X-ray photoelectron spectroscopy showed that the Raman spectra of the 2nd and 3rd graphene interlayer precursors were similar to those of other acceptor-type graphene intercalation compounds, and the inner and outer carbon networks E2g2 mode frequency is different.
