PANI Incorporated Fe-MOF: As an Electrode Material for Supercapacitor

Abstract

A novel composite of Fe-metal organic framework (Fe-MOF) and polyaniline (PANI) was synthesized using a cost-effective and rapid hydrothermal method. Structural characterization confirmed the successful incorporation of granular PANI over the Fe-MOF surface, which was examined through X-ray diffraction (XRD), scanning electron microscopy (SEM), and Raman spectroscopy. The Fe-MOF@PANI electrode demonstrated a high specific capacitance of 234.6 F g⁻¹ at 1 A g⁻¹ and 87% capacitance retention after 400 cycles at 10 A g⁻¹. Key features of the synthesized nanocomposite include scalability, high porosity, long-term stability, good conductivity, low charge transport resistance, and a fast charge-discharge rate. This study highlights Fe-MOF@PANI as a promising electrode material for supercapacitors.
