TEHREEM FAKHAR2025-11-202025-11-202025https://escholar.umt.edu.pk/handle/123456789/11032The fast exhaustion of fossil fuels and the growing energy demand in the world has led to the need to come up with efficient, renewable and eco-friendly energy storage systems. The supercapacitors are one of the technologies that have received a lot of attention because of their high power density, high charge discharge rate, and long cycle life. Their performance is however very much dependent on the electrode material employed. Metal-organic frameworks (MOFs) due to their high surface area, tunable pore structure, and high chemical stability have become promising electrode materials of the next-generation supercapacitor. In the study, copper metal-organic framework (Cu-MOF) was effectively prepared by a simple solvothermal synthesis with copper nitrate trihydrate and terephthalic acid in a solution of N,N-dimethylformamide (DMF)-ethanol mixture. It was selected based on the synthesis pathway as it was simple and cost-effective with the capacity to make well-defined crystalline structures. The synthesized Cu-MOF was examined using the X-ray diffraction (XRD) and scanning electron microscopy (SEM). XRD analysis verified the crystalline structure of Cu-MOF whose average crystallite size was around 27nm and d-spacing was 0.96nm. The morphology was found to be porous and almost spherical with the help of SEM images. Comprehensively, the research has shown that the easily prepared Cu-MOF is one of the most promising electrode materials in supercapacitors which combine to a great deal in terms of high capacitance, structural stability, and green synthesis, which can be applied in future energy storage systems.enThesis
