In this work, we derived a γ-Zn(OH)2/Zn(OH)2.0.5H2O/Zn(OH)2@AC nanocomposite-based electrode material from ZIF-8 metal-organic framework (MOF) /activated charcoal with a weight ratio of 1:0.5 by a simple thermolysis process at 400 °C for 4 h. The structural, morphological, and electrochemical properties of the prepared electrode materials were studied using powder XRD, FE-SEM, TEM, XPS, and electrochemical workstations. The electrochemical properties were studied in three-electrode cells with 3M of KOH electrolyte. The specific capacitance of γ-Zn(OH)2/Zn(OH)2.0.5H2O/Zn(OH)2@AC was 560 F/g @1 A/g current density, and it was higher than that of ZIF-8 metal-organic framework (MOF) /activated charcoal (330 F/g @ 1 A/g). The enhanced specific capacitance of γ-Zn(OH)2/Zn(OH)2.0.5H2O/Zn(OH)2@AC is due to the improved electrical conductivity o along with higher active surface area which increased the contact of electrolyte ions with active sites along with electron transportation.
