Using the synergistic effect of Cu nanoparticles (NPs) and N‐doped graphene, we report a highly efficient, green, and recyclable heterogeneous catalytic system for the functionalization of inert C(sp³)–H bonds with oxygen; this system has significantly higher activity than the N‐free Cu catalyst. The synergistic effect of the Cu NPs and N‐doped graphene is also unambiguously elucidated.

铜纳米粒子/ N掺杂石墨烯的协同效应对惰性C（sp3）–H键的高效催化氧化

利用铜纳米颗粒（NPs）和N掺杂石墨烯的协同效应，我们报道了一种高效，绿色和可循环利用的非均相催化体系，用于惰性C（sp ³）-H键与氧的功能化；该系统比不含N的Cu催化剂具有更高的活性。Cu NP和N掺杂的石墨烯的协同作用也得到明确阐明。
