摘要
以氧化石墨烯分散液、硫代乙酰胺与水合钼酸铵为原料,采用水热法制备了石墨烯/二硫化钼复合物.通过扫描电镜(SEM)、红外光谱(FT-IR)、紫外可见光谱(UV-Vis)和X射线衍射分析(XRD)对复合物进行形貌及结构分析,发现石墨烯与二硫化钼形成团簇状复合物.循环伏安法(CV)等电化学测试表明:石墨烯的加入提高了石墨烯/二硫化钼复合物的比电容.当石墨烯与二硫化钼质量比为1∶1时,比电容最大为0. 47 F/g.
Graphene/molybdenum disulfide composites were prepared by hydrothermal method with graphene oxide aqueous dispersion, thioacetamide and ammonium molybdate as raw materials. The structure and morphology of the samples were characterized by SEM,FT-IR,UV-Vis,and XRD. It was found that the obtained graphene/molybdenum disulfied composites has been formed into clusters. Cyclic voltammetry(CV) and other electrochemical measurements showed that the specific capacitance of graphene/molybdenum disulfide composites increased with the addition of graphene. The highest specific capacitance of the composites was 0. 47 F/g,when the mass ratio of graphene to molybdenum disulfide was 1∶1.
