How fast is the reaction of hydrated electrons with graphene oxide in aqueous dispersions?

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...

Description
Summary: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).
