Synergistic Integration Nanoarchitectonics of Zn-MOF and Poly(1-Amino-9, 10-anthraquinone) for Enhanced Capacitor Performance

Abstract The increasing concern regarding energy demand has emerged as a significant issue for various industries, including industry and transportation. Capacitors have recently emerged as a novel approach to address the worldwide energy shortage. Consequently, we have created novel materials for capacitor uses. A composite of poly aminoanthraquinone (PAAQ) and Zinc-based metal organic framework (Zn-MOF) was employed for high-capacitance applications. Comparative studies were conducted on PAAQ and Zn-MOF. Accordingly, Zn-MOF was added to PAAQ using both layer structure (GC/PAAQ/Zn-MOF and physical mixing (GC/PAAQ-Zn-MOF). The modified glassy carbon electrode’s structure and morphology were examined using X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Analysis (EDAX), Elemental Mapping, and Ultraviolet-Visible Spectroscopy (UV-Vis). The modified electrodes exhibited a high capacitance when examined in 1.0 M H 2 SO 4 equal 180, 298, and 330 F/g@1 A/g for GC/PAAQ, GC/PAAQ/Zn-MOF, and GC/PAAQ-Zn-MOF; respectively. Furthermore, the rate of capability was calculated as 81, 71, and 91% for GC/PAAQ, GC/PAAQ/Zn-MOF, and GC/PAAQ-Zn-MOF, respectively.
