| 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 mAh?g-1 at 1 A?g-1. The hybrid supercapacitor (HSC) based on NiCo-LDH electrode and activated carbon (AC) achieves a specific energy of 27.39 Wh?kg-1 with excellent cycling stability (capacity retention of 93.5% after 5000 cycles). |
