本实验利用电化学的方法，在酸性条件下，以石墨片为负极，铂丝电极为正极，在一定电压下电解得到剥离石墨烯（EEG）。然后将Pt的前驱体H2PtCl6?6H2O与超声分散好的EEG混合，溶剂热还原得到剥离石墨烯负载铂的催化剂（EEG-Pt）。通过运用X射线衍射仪（XRD）、扫描电子显微镜（SEM）和透射电子显微镜（TEM）分别对催化剂的组成、结构和形貌进行表征。通过傅里叶红外光谱（FTIR）、X-射线光电子能谱（XPS）和拉曼光谱（Raman）对材料的含氧量进行分析。利用循环伏安法（CV）完成催化剂对甲醇催化氧化性能的测定。 与传统的氧化石墨烯（GO）相比，电化学剥离石墨烯具有高导电性、表面含氧官能团少、低缺陷等优点。因此，用剥离石墨烯负载的Pt 纳米颗粒比传统方法制备的石墨烯负载的Pt纳米颗粒分散性更好，粒径更小，具有更好的电催化性能。 本研究提出了一种新型的石墨烯负载铂纳米催化剂的制备方法，为甲醇燃料电池阳极催化剂的研究提供了有益的补充。

In this work, electrochemically exfoliated graphene (EEG) was successfully obtained by electrochemical exfoliated method in acidic conditions at a certain voltage，in which graphite sheet woks as the negative electrode and platinum wire as the anode electrode. Then EEG was used to prepare electrochemically exfoliated grapheme-based platinum catalyst (EEG-Pt) through solvothermal method. X - ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were employed to characterize the crystal structure and morphology of the catalysts. The oxygen content of the material was analyzed by Fourier transform infrared spectroscopy (FTIR), Raman and X-ray photoelectron spectroscopy (XPS). The catalytic activity for methanol oxidation was investigated by cyclic voltammetry (CV). Compared with the graphene (G) prepared by the reduction of the traditional graphene oxide(GO), the electrochemically exfoliated graphene（EEG）has the advantages of high conductivity, less oxygen-containing functional groups and low defects. The particle size of Pt nanoparticles on the surface of electrochemically exfoliated graphene is much smaller than that of Pt nanoparticles on the surface of graphene prepared by the same method except distilled water was used instead of DMF. EEG-Pt has better electrochemical activity and stability than rGO-Pt. In this study, a new method of electrochemically exfoliated graphene based platinum catalyst was proposed, which offers a valuable addition to the study of methanol fuel cell anode catalyst.
