Synthesis and Characterization of NiCo₂S₄-MOF-ZIF-67@rGO for Efficient Electrochemical Energy Storage

A nanocomposite, NiCo 2 S 4 -MOF-ZIF-67@reduced grapheme oxide was produced via a straightforward and scalable hydrothermal process. The product nanocomposite was characterized using different techniques including Infra red spectroscopy, X-ray diffraction analysis, scanning electron microscopy and electrochemical measurements. This nanocomposite was found to be composed of NiCo 2 S 4 nanoparticles embedded in a MOF-ZIF-67 matrix, which was anchored onto rGO sheets. The NiCo 2 S 4 -MOF-ZIF-67@rGO nanocomposite exhibited excellent electrochemical performances. These properties make the NiCo 2 S 4 -MOF-ZIF-67@rGO nanocomposite a potential electrode substance in the case of electric energy accumulators and conversion devices such as primary and rechargeable Li cells and high performance ultra-capacitors. The simple and scalable synthesis method used in this study also suggests that this material has potential for large-scale production.
