Structural characterization and Supercapacitor Application of Green Synthesized Fe2O3 Nanospindles using Palmyra palm extract

Abstract

Iron oxide nanospindles (IONSs) were synthesized by greener route assisted with Palmyra palm (PP) extract. The synthesized IONSs were characterized by FTIR, XRD, EDAX, SEM and TEM techniques. FT-IR results confirmed the nanosystem formation and the presence of the phytochemical constituents on the surface of prepared nanosystems. XRD analysis confirmed the crystalline state of synthesized iron oxide nanospindles with the size range of about 7.76 nm. Morphological analysis of the iron oxide from SEM and TEM results revealed the spindle like morphology. Working electrodes fabricated from the active material Fe₂O₃ nanospindles were studied through CV, GCD and EIS techniques to investigate their electrochemical behaviour. The prepared Fe₂O₃ electrode shows good electrochemical properties with maximum specific capacitance of 350.66 F/g and very low charge transfer resistance of 0.81Ω.
