Investigation of surfactant assisted Fe2(MoO4)3/rGO nanocomposite for supercapacitor application

Utilizing a hydrothermal method with PEG-6000 as a surfactant material, this study presents the synthesis of Fe2(MoO4)3 nanoparticles and their nanocomposites with carbonaceous material in the form of rGO. Comprehensive fundamental characterization studies, including XRD, Raman, and FTIR, confirm the monoclinic crystal structure of Fe2(MoO4)3 and its nanocomposites. Nanorod-structured Fe2(MoO4)3/PEG/rGO exhibits a surface area of 78.571 m2/g with pore volume of 0.202 cc/g. Electrochemical analyses, employing techniques such as Cyclic Voltammetry (CV), Galvanostatic Charge-Discharge (GCD), and Electrochemical Impedance Spectroscopy (EIS), underscore the remarkable performance of the synthesized electrodes. Notably, the Fe2(MoO4)3/PEG/rGO electrode exhibits a specific capacitance of 575.13F/g at a scan rate of 10 mV/s and demonstrates significant cyclic retention over 20,000 cycles at a current density of 20 A/g in GCD analysis. This work highlights the promising electrochemical attributes of Fe2(MoO4)3/PEG/rGO electrodes, showcasing their potential for high-performance supercapacitor applications.
