Solvothermal synthesis of Ni-Co-metal organic framework (MOF)/graphene nanoplatelets (GNPs) nanocomposites was done for their potential application as electrode material in energy storage devices. Addition of GNPs and metallic precursors together with 2-methylimedazole in the same autoclave reactor produced smooth-nanoflakes like Ni-Co-MOF/GNPs nanocomposites as evaluated by scanning electron microscopy (SEM). X-ray diffraction (XRD) analysis showed the presence of GNPs where GNPs do not affect the growth of MOF crystals and Ni-Co-MOF crystalline phases remain unaffected in the composite structure. Fourier transform infrared (FTIR) spectroscopy analysis confirmed the presence of organic links forming nickel-cobalt metal cations framework. Electrochemical testing (CV, EIS and GCD) of the produced composites demonstrated that GNPs addition can enhance the charge storage …
