摘要:

利用蔗糖和乙醇作为碳源,以氯化镍高温还原形成的镍颗粒作为模板,制备了泡沫状石墨烯多孔材料。 继而以其作为载体,通过浸渍和高温热解法制备了泡沫状MoS2/石墨烯二维复合材料。 通过扫描电子显微镜(SEM)、透射电子显微镜(TEM)、拉曼光谱、X射线衍射(XRD)等技术手段研究了复合材料的形貌、组成和结构。 循环伏安、恒流充放电和循环寿命测试均表明,该材料具有良好的超级电容器性能,质量比电容达203.5 F/g,面积比电容达280 mF/cm2,5000次恒流充放电循环后的电容保持率约80%。

Abstract:

Using nickel particles formed in a high-temperature treatment of nickel chloride as a template, sucrose and ethanol as carbon sources, the bubble foam-like porous graphene films were prepared. Using the obtained porous graphene films as the substrate, a MoS2/graphene 2D bubble foam-like hybrid was prepared through an impregnation-anneal method. The morphology, composition and structure of the material were studied by scanning electron microscope(SEM), transmission electron microscope(TEM), Raman spectroscopy, and X-ray diffraction(XRD). Electrochemical tests indicate that the obtained bubble foam-like MoS2/graphene 2D hybrid has excellent supercapacitor performances with a specific capacitance of 203.5 F/g, an areal capacitance of 280 mF/cm2 as well as a high capacitance retention of ~80 % after 5000 charge/discharge cycles.
