摘　　要：以Hummers法为基础一步合成了氧化石墨烯,并制备了羧基化石墨烯.用热失重、红外光谱法、XRD衍射以及扫描电子显微镜对羧基化石墨烯的官能团及结构进行了表征.并用循环伏安法和差分脉冲伏安法进行了电化学性能分析.结果表明制备的羧基化石墨烯不但具有较好的水溶性,而且具有较好的电催化作用.This research synthesized graphene oxide and carboxyl graphene oxide based on Hummers method. The structure and properties of carboxylated grapheme were analyzed with thermogravimetry, Fourier transform infrared spectrophotometer, X-ray diffraction spectroscopy and scanning electron microscope. The electrochemical properties were detected by the cyclic vohammetry method and the differential pulse vohammetry method. The results show that the carboxylated grapheme not only has better solubility in water, but also has better catalysis.
