中文摘要： 石墨烯(Graphene, Gr)，是由sp2杂化的碳原子紧密堆积成单层二维蜂窝状晶格结构，是构建其他各维数的碳材料的基本单元。本项目针对石墨烯传统制备方法的不足，结合已有的石墨烯负载磁性金属纳米离子研究基础，采用在Hummer法基础上改进的液相还原-高温炭化法制备该材料，不断优化配方及制备工艺，为低成本大规模制备稳定的石墨烯负载金属纳米离子复合材料积累经验和理论基础，并运用XRD、XPS、Raman、EDS等技术结合相关的界面理论及模型探究石墨烯负载Fe\Co\Ni\Cu等金属纳米离子的界面结构与材料电化学催化机理间的内在规律，并在此基础上进一步探索金属纳米粒子与石墨烯之间协同效应可能产生的新的性能和用途。研究成果将会为石墨烯负载的进一步研究提供理论依据和技术基础。

英文摘要： Carbon encapsulated metal nanoparticles (CEMNPs) is a new type of new carbon materials, which is the basic unit of carbon material in the construction of the other dimension. according to the disadvantages of traditional method,A new methord was based on liquid phase reduction and carbonization of the materials preparation,Material formulations and process were further optimized.For low-cost preparation of CEMNPs with high performance，the experimental data and theoretical basis was accumulated and established. The phase, morphology, and structure of as-prepared samples were characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM), Raman spectroscopy (Raman), X-ray photoelectron spectroscopy analysis (XPS) and energy spectrum (EDS) respectively. Inherent law of interface and catalysis applications of graphene decorated with metal nanoparticles(Fe\Co\Ni\Cu) was researched.The new applications and prorerties of CEMNPs was researched for the synergistic effect.The theoretic basis and the technical basis for further research of CEMNPs will be provided by the research results in this project.
