Abstract
In this research work, hematite (α-Fe2O3) nanoparticle, and oxidized graphene (OG) were prepared, and then mixed to form stable suspension of α-Fe2O3/OG nanocomposite. Different characterization techniques were used to explore the chemical and physical properties of the α-Fe2O3/OG nanocomposite including XRD, FT-IR, and UV-Vis. The results revealed the successful formation of the α-Fe2O3 nanoparticles, and the oxidation of the MWCNT, as well as the formation of stable α-Fe2O3/OG nanocomposite. The electrochemical behaviour of the α-Fe2O3/OG nanocomposite were investigated using cyclic voltammetric (CV), and linear sweep voltammetry (LSV) and the results revealed that modification of α-Fe2O3 nanoparticles with OG greatly enhanced the electrochemical performance, and capacitive behaviour, as well as the cycling stability.
