Characterization of graphene oxide and reduced graphene oxide coating on gold electrodes by impedance spectroscopy

Abstract

In this study, the impedance spectroscopy is used as a detection tool in order to characterize graphene oxide and reduced graphene oxide coating on the gold surfaces. Gold surfaces are chosen as commercial surface electrodes. The impedance of redox solution through bare gold electrodes, graphene oxide and reduced graphene oxide coated gold electrodes is measured.
