Abstract

Understanding the mechanism of the reduction of graphene oxide (GO) is a key-question in graphene related materials science. Here, we investigate the kinetics of the reaction of radiolytically generated hydrated electrons with GO in water. The electron transfer proceeds on the ns time scale and not on the ps time scale, as recently reported by Gengler et al. (Nat. Commun., 2013, 4, 2560).
