Abstract

Electrode materials for supercapacitors, sensors, and battery applications were frequently manufactured using the chemistry of metal organic framework nanostructured materials. These materials have three-dimensional networks between organic linkers and metal precursors thanks to diverse chemical alterations. Due to their enhanced surface characteristics, porous nature, and strong connecting organic molecules for numerous possible applications, MOFs have a wide range of uses. In this study, we used a sonicated enhanced hydrothermal reaction to fabricate ZnCo2S4 and ZnCo2S4 on the metal organic framework composite materials. Raman, FTIR, XRD, XPS, SEM, and SEM-EDS tests were utilized to confirm the composite's structural and morphological features. With 1 M KOH electrolyte, composite electrodes for supercapacitor fabrication were produced. The composite electrodes have a stability under cycles count of 5000 and a capacitance of 550 F/g at a density of 1 A/g.
