We demonstrate a photochemical reaction between graphene and benzoyl peroxide. This reaction introduces spatially localized defects into the graphene basal plane. The reactivity of the single-layer graphene is approximately 14 times higher than that of the double-layer graphene. Our result suggests that photoexcited graphene transfers a hot electron to benzoyl peroxide and induces its decomposition to a phenyl radical.
我们展示了石墨烯和过氧化二苯甲酰之间的光化学反应。该反应在石墨烯基面中引入了局域缺陷。单层石墨烯的反应活性大约是双层石墨烯的 14 倍。我们的结果表明，光激发的石墨烯将一个热电子转移给过氧化二苯甲酰，并促使其分解为一个苯基自由基。
