    Synthesis of ternary metal oxides with carbon composite as high-performance electrode materials
    (UMT, Lahore, 2024) Meishaar Hussain
    This study involves the synthesis of two samples with the variation of molar concentration of a ternary Zirconium-Nickel-Cobalt ZIF-67 composite (ZrNiCo ZIF 67) using the co-precipitation method. The samples vary in the molar concentration of ZrO (NO3)2, Ni (NO3)2, Co (NO3)2, and BTC (C9H6O6). The composite is generated from MOF. Both of these samples have undergone electrode manufacturing. The features of ternary metal oxides ZIF 67, such as their high surface area, porosity, chemical stability, adjustable qualities, redox activity, and eco-friendliness, have made them a promising material for supercapacitor electrodes. The charge storage capacity of ZrNiCo ZIF-67 is significantly enhanced by its porous polyhedral structure, which contains linked nanoparticles of varying compositions. They are economically, ecologically, and socially significant, and they are fundamental to a strong and sustainable energy future. When evaluating the performance of the electrode, many characterizations are employed, such as X-ray diffraction, and electrochemical methods like cyclic voltammetry (CV), galvanostatic charge and discharge (GCD), and electrochemical impedance spectroscopy (EIS). At a current density of 1 A/g, the ZrNiCo ZIF-67 (2:1) electrode material outperforms the other ZrNiCo ZIF-67 (1:1) materials with a specific capacitance of 247 F/g. As electrode materials for supercapacitor applications, these studies give a straightforward and effective way to generate nanocomposites ZrNiCo ZIF-67 (2:1) with enhanced electrochemical properties.
