了解氧化石墨烯(GO)的还原机理是石墨烯相关材料科学的一个关键问题。在这里,我们研究了放射性生成的水合电子与氧化石墨烯在水中的反应动力学。最近由Gengler等人报道,电子转移在ns时间尺度上进行,而不是在ps时间尺度上进行。浙江农业学报,2013,4,2560)。
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).
