Abstract
This study aims to develop nanostructured materials based on metal-organic frameworks (MOFs) with high porosity that can be utilized as efficient supercapacitor materials. The materials, Zinc-Nickel-Cobalt ZIF-67 derivatives with varying ratios of Zn and Ni, were synthesized through the co-precipitation method. The MOFs are crystalline materials with high porosity and are composed of metal ion chains linked by organic ligands. Electrodes were fabricated using mesoporous carbon and three samples were prepared with different Zn and Ni ratios, including 1:1, 1:2, and 2:1. These samples were then characterized using techniques such as X-Ray diffractometer (XRD), Raman and Fourier Transform Infrared Spectroscopy (FTIR), Galvanostatic charge-discharge (GCD), cyclic voltammetry (CV), Electrochemical Impedance Spectroscopy (EIS), BET. These characterization techniques were used to determine the crystalline structure, bonding structure, and electrochemical behavior of the samples. The results of this study will contribute to the development of advanced materials for supercapacitor applications and could lead to significant improvements in energy storage technology.
