Abstract:
A well-designed cobalt-based metal organic framework (Co-MOF) derived NiCo layered double hydroxides (NiCo-LDH) three-dimensional porous nanostructures has been fabricated on carbon cloth (CC) by the ion etching/exchange reaction method. The morphology and structure of the synthesized samples have been characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). As an electrode, the optimal NiCo-LDH shows a high specific capacity of 226.3 mA·h/g at 1 A/g. The hybrid supercapacitor (HSC) based on NiCo-LDH electrode and activated carbon (AC) achieves a specific energy of 27.39 W·h/kg with excellent cycling stability (capacity retention of 93.5% after 5000 cycles).

中文说明:

采用离子刻蚀/交换反应法制备了钴基金属有机骨架(Co-MOF)衍生的NiCo层状双氢氧化物(NiCo-LDH)三维多孔纳米结构。采用X射线衍射(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)和X射线光电子能谱(XPS)对合成的样品进行了形貌和结构表征。作为电容器正极,优化后的NiCo-LDH样品在1 A.g-1时具有226.3 mAh.g-1的高比容量。基于NiCo-LDH正极和活性炭(AC)负极的混合超级电容器(HSC)比能达到27.39 Wh.kg-1,并且具有较好的循环稳定性(5000次循环后容量保留率为93.5%)。
