Influence Of Graphene Oxide Amount on The Structure and Morphology of In2O3-Reduced Graphene Oxide Composite Film

In this study, indium oxide-reduced graphene oxide (In2O3-rGO) composites were produced in one-pot using an electrochemical technique for the first time. The effect of graphene oxide (GO) amount on the composition and morphology of the composite structure was investigated. For this purpose, electrolyte solutions containing GO and In3+ ions were mixed at different volume ratios. Deposits were carried out at constant potential in different electrolyte compositions. The characterizations of the composite structures prepared under different experimental parameters were investigated using X-ray diffraction spectroscopy (XRD), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, and field effect scanning electron microscopy (FESEM) techniques. It was concluded that the In2O3-rGO composite with the best composition was obtained in 1:1 GO: In3+ electrolyte by volume.
