Abstract

In this paper, the physicochemical characterization and electrochemical behavior of a newly developed silver nanoparticle-incorporated magnetite/reduced graphene oxide (Ag-Fe3O4/rGO) are presented. The composites were synthesized by a simple approach of synthesis route combining the Hummer’s method for synthesis of graphene oxide and the co-precipitation method for preparation of iron oxide. The physical characterization of the composites was studied using Fourier Transform Infrared (FTIR) spectroscopy, X-Ray Diffraction (XRD) analysis, Scanning Electron Microscopy (SEM), and Brunaeur-Emmet-Teller (BET) technique. Cyclic voltammetry (CV) technique and Electron Impedance Spectroscopy (EIS) were employed to study the electrochemical properties of Ag-Fe3O4/rGO. Results from the analyses signify a good electron transfer characteristic with high conductive and excellent capacitor nature of the modified electrocatalyst.
