Studies on Synthesis and Characterization of Advanced Electrode Material Nanocomposite of Tetra Metal Oxides of Fe-Mn-Ni-Co-ZIF-8@rGO

The growing demand for efficient and sustainable energy storage systems has accelerated the development of advanced electrode materials for high-performance supercapacitors. In this study, novel nanocomposite electrodes based on zeolitic imidazolate framework-8, Fe-Mn-Ni-Co tetra-metal oxides and reduced graphene oxide were designed, synthesized and characterized to enhance electrochemical energy storage performance. The synthesized materials were systematically characterized using Fourier Transform Infrared Spectroscopy and X-ray Diffraction techniques. FTIR analysis confirmed the coexistence of characteristic organic functional groups of ZIF-8 and metal-oxygen vibrations of transition metal oxides, indicating successful hybrid composite formation. XRD studies revealed the crystalline nature and phase purity of ZIF-8 along with the formation of nanocrystalline Fe-Mn-Ni-Co oxide structures. The presence of multiple transition metal ions generated lattice distortions and increased the density of electroactive sites, thereby facilitating enhanced redox reactions. Overall, the study demonstrates that ZIF-8-derived Fe-Mn-Ni-Co oxide/rGO nanocomposites are promising electrode materials for next-generation supercapacitors
