中文摘要：

采用元素分析、红外光谱（FTIR）、X射线光电子能谱（XPS）、拉曼光谱、X射线衍射（XRD）、固体^13C核磁共振波谱（^13CMASNMR）、热失重分析（TGA）、导电率测试以及原子力显微镜（AFM）等手段对正丁基氯化镁还原的氧化石墨烯进行了系统的表征．结果表明，正丁基氯化镁可以有效还原氧化石墨烯，随着其用量的增加，氧化石墨烯还原程度增加，碳／氧摩尔比升高，片层间距减小，热稳定性增强，导电率增大（可达3．6×10^2S／m）．还原后部分氧化石墨烯片层发生聚集．

英文摘要：

Graphene oxide reduced by n-butylmagnesium chloride （n-BuMgC1） has been characterized sys- tematically by elemental analysis, Fourier transform infrared spectroscopy （FTIR）, X-ray photoelectron spectroscopy （ XPS）, Raman spectroscopy, X-ray diffraction （ XRD）, solid-state 13 C nuclear magnetic resonance （13C NMR）, thermal gravimetric analysis（TGA）, electrical conductivity measurement and atomic force microscopy （AFM）. The results indicate that n-BuMgC1 has a good efficiency in the reduction of graphene oxide. With the increase of n-BuMgC1 concentration, the C/O molar ratio of the reduced graphene oxide （rGO） increased, and the interlayer distance of the rGO sheets decreased. The thermal stability of rGO has been im- proved significantly and the electrical conductivity of rGO increased to 3.6×10^2 S/m. AFM images show that the thickness of rGO sheets is larger than that of GO due to aggregation.
