Effect of Concentration Variation on Zirconium Nickel Cobalt Metal Organic Framework-Based Electrode Material

In this research, two samples of a ZrNiCo ZIF-67 with the change in molar concentration of metal to linker (1:1 and 1:2) were synthesized via the co-precipitation method. Then electrode fabrication was done. An attractive candidate for supercapacitor electrodes, ternary metal oxides ZIF 67 exhibit several desirable properties, including a large surface area, porosity, chemical stability, tailoring ability, redox activity, and low environmental impact. The porous polyhedral structure of ZrNiCo ZIF-67, which incorporates connected nanoparticles of varied compositions, greatly enhances the charge storage capacity. They are essential to a robust and sustainable energy future, and they have social, ecological, and economic significance. Electrochemical methods such as cyclic voltammetry (CV), galvanostatic charge and discharge (GCD), and electrochemical impedance spectroscopy (EIS) are among the various characterizations used to assess the electrode's performance. Other approaches include X-ray diffraction to study the crystal structure. With a specific capacitance of 232 F/g at a current density of 1 A/g, the ZrNiCo ZIF-67 (1:2) electrode material performs better than the other ZrNiCo ZIF-67 (1:1) materials. In order to create nanocomposites ZrNiCo ZIF-67 (1:2) with improved electrochemical characteristics, this research provides an easy and practical method. These materials can then be used as electrodes in supercapacitors for high specific capacitance
