我们证明了石墨烯和过氧化苯甲酰之间的光化学反应。该反应将空间局部缺陷引入石墨烯基面中。单层石墨烯的反应性比双层石墨烯的反应性高14倍。我们的研究结果表明，光激发石墨烯转移热电子过氧化苯甲酰，并诱导其分解为苯基自由基。
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 similar to 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.
