摘要
利用水热法合成了MnO_(2)纳米棒以及10%碳纳米管(CNTs)/MnO_(2)纳米棒复合材料,并制备成电极。利用扫描电子显微镜观察制备材料的表面形貌,X射线衍射仪分析制备材料的物相结构,采用循环伏安曲线和恒电流计时电位曲线测试所制备材料在0.5 mol/L Na_(2)SO_(4)溶液中的电容性能。结果表明,制备的MnO_(2)主要为多晶纳米棒状结构。10%CNTs与MnO_(2)复合后,材料的比电容得到较大提高,最高达到249 F/g。
MnO_(2) nanorods and 10%carbon nanotubes(CNTs)/MnO_(2) nanorod composites were synthesized using hydrothermal method and prepared into electrodes.The surface morphology of the prepared material was observed using scanning electron microscope,and the phase structure of the prepared material was analyzed by X-ray diffraction.The capacitive performance of the prepared material in a 0.5 mol/L Na_(2)SO_(4) solution was tested using cyclic voltammetry and constant current chronopotentiometry curves.The results show that the prepared MnO_(2) mainly consists of polycrystalline nano rod like structures.After the composite of 10%CNTs and MnO_(2),the specific capacitance value of the material was greatly improved,reaching a maximum of 249 F/g.
