제목 Influenceof urea precursor concentration on electrochemical properties of Ni-Co basedmetal organic framework electrodes for supercapacitors​
초록 In supercapacitor, composite of NiCo MOF and Urea as a surfactant is synthesized in one-pot by hydrothermal method. Adding Urea to the NiCo MOF makes interstitial gaps and ultra-thin nano structure in the NiCo MOF structure and improve charge transfer ability. We have obtained the optimal ratio of metal and surfactant to give the best specific capacitance. It was used as working electrode material in three electrodes system. Field emission scanningelectron microscopy (FE-SEM), x-ray diffraction (XRD), fourier transforminfrared (FT-IR) spectroscopy analyzed microstructures and morphologies of thecomposites. Also, cyclic voltammetry (CV), galvanostatic charge-discharge (GCD)and electrochemical impedance spectroscopy (EIS) curves were used to analyze the electrochemical properties of the composites in 6M KOH electrolyte.
