Abstract

We report the observation of oscillatory redox reactions on the surface of multilayer graphene oxide (GO) films at room temperature. The redox reactions exhibited dampened oscillatory behavior with a period of about 5 days and were found to be dependent on the time elapsed from film deposition. The kinetic behavior observed for the oxidation–reduction reactions and the metastability of the surface functional groups are adequately described by two models involving GO reactions and reactant diffusion.
