中文摘要：
采用环境友好型还原剂柠檬酸钠,成功实现了温和条件下氧化石墨（GO）的控制还原,制备得到了石墨烯材料。利用扫描电子显微镜（SEM）、X-射线衍射（XRD）、紫外可见吸收光谱（UV-vis）、傅立叶红外光谱（FT-IR）等对所得产物进行了分析表征,并研究比较了氧化石墨与氧化石墨烯还原产物（RGO）的电子输运性能。结果表明：柠檬酸钠可在温和条件下还原氧化石墨得到高质量的石墨烯。
英文摘要：
Graphene was produced from graphene oxide using sodium citrate as the reducing agent under mild conditions.The products were characterized by scanning electron microscopy,X-ray diffraction,ultraviolet visible absorption spectroscopy and Fourier transform infrared spectrometry.Results indicate that the electrical conductivity of graphene oxide was increased by over three orders of magnitude after reduction with sodium citrate,and the obtained graphene showed nonlinear I-V curves.
