Abstract

In this study, gold nanomaterials were used as an additive for iron electrodes to improve its cyclability in alkaline solutions. The morphology of gold nanoparticles was investigated via transmission electron microscopy (TEM) measurement. To evaluate the role of additive gold nanomaterials in iron electrodes, cyclic voltammetry (CV) measurements were performed on Fe2O3/Au and Fe2O3/Au/AB (AB - acetylene black) electrodes using various amounts of nanogolds. The results show that the amount of nanogolds and AB strongly affects the electrochemical characteristics of the iron electrodes. AB helps increase the electrical conductivity of Fe2O3/Au/AB electrodes while gold nanoparticles show positive effects on the oxidation reaction of iron.
