Abstract
Reduced graphene oxide/iron oxide (rGO/Fe3O4) nanocomposite was synthesized by facile one-pot process and its performance as electrocatalyst for oxygen reduction reaction (ORR) was investigated. The nanocomposite was physically and electrochemically characterized using Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), Brunauer–Emmett–Teller (BET) method, scanning electron microscopy (SEM), cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS). FT-IR, XRD, and SEM confirms the presence of rGO and Fe3O4 as whole. CV data shows increment in current responses nearly two and a half folds for rGO/Fe3O4/GCE. EIS analysis shows stable electron transfers with lower charge transfer resistance (Rct) of modified electrode due to synergistic effect between rGO and Fe3O4. The performance of the electrocatalyst in ORR was compared with bare GCE and rGO/GCE where higher catalytic performance and better stability were obtained. The analysis results shows that the compound could be a promising material for fuel cells.
