【摘要】 还原氧化石墨(rGO)具有类石墨烯性质，并且具有成本低、产率高的优势，因此在生物、环境、光电、储能等领域有广泛的应用前景。自1859年发现氧化石墨(GO)以来，对于GO以及衍生物结构的研究也未间断过。通过变温X射线衍射测量干燥GO的X射线衍射图样(XRD)。测量石墨，80℃、150℃以及200℃热还原氧化石墨的XRD图样，GO的傅里叶变换红外光谱(FTIR)。聚焦GO在还原过程中结构的变化。GO是乱堆叠结构，典型的XRD图样中包括(00m)和(hl0)峰，但没有三维(hlm)峰。Warren–Bodenstein (WB)方程可以很好的解释这一现象。还原氧化石墨具有不均一结构，该结构由类石墨烯基面组成，基面上有结构缺陷，并分布着含有氧化基团的区域。更多还原

【Abstract】 The graphene-like properties make reduced graphene oxide a highly desirable material to be used in a plethora of sensorial, biological, environmental or catalytic applications as well as optoelectronic and storage devices. Since the discovery of graphite oxide(GO) in 1859, research on the structure of GO and its derivatives has never ceased. We measured the X-ray diffraction(XRD) pattern of dried GO using variable temperature XRD. We also measured the XRD patterns of graphite, thermally reduced graphite oxide at 80 ℃, 150 ℃, and 200 ℃, as well as the Fourier transform infrared spectroscopy(FTIR) of GO. We focused on the structural changes of GO during the reduction process. GO has a disordered stacking structure, and its typical XRD pattern includes(00 m) and(hl0) peaks, but lacks a three-dimensional(hlm) peak. The Warren–Bodenstein(WB) equation can well explain this phenomenon. Reduced graphene oxide possesses a heterogeneous structure comprised of a graphene-like basal plane that additionally decorated with structural defects and populated with areas containing oxidized chemical groups.更多还原
