| 摘 要： | 采用溶剂热法成功制备了纳米CuFe_2O_4-rGO复合材料。通过X射线衍射(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)和电化学工作站对样品的结构、形貌及电容特性进行表征。结果表明,CuFe_2O_4纳米粒子均匀地分散在石墨烯片层间,其中CuFe_2O_4-20%rGO复合材料具有最优的电化学性能,当电流密度1 A·g~(-1)时,其比电容为1 952.5 F·g~(-1),当电流密度为1 A·g~(-1)时,CuFe_2O_4-20%rGO复合材料经1 000次充放电后的比电容保持率为86.17%。

| Abstract: | Nano CuFe2O4-rGO composites were successfully prepared by solvothermal method. The phase structure, morphology and capacitance of the sample were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and electrochemical workstation, respectively. The results indicated that the CuFe2O4 nanoparticles were uniformly dispersed in the graphene nanosheets, and the CuFe2O4-20%rGO composite shown the best electrochemical performance. When the current density is 1 A·g-1 the specific capacitance of the CuFe2O4-20% rGO composite was 1 952.5 F·g-1, and shown an excellent cycling stability along with 86.17% specific capacitane retained after 1 000 cycle tests. |
