Metal nanoparticles (NPs) stabilized by MOFs are very promising for catalysis, whereas introduction of C into MOFs has been very rarely used, and there was no report for their cooperative catalysis in organic syntheses. In this work, C @UiO-67 was synthesized by a one-pot method, so that C is uniformly distributed on UiO-67 in molecular form. Pd NPs coordinating with C have been successfully embedded into the framework. The obtained multifunctional C Pd @UiO-67 catalyst exhibits remarkable synergistic catalytic activity in cascade reactions under mild conditions, where UiO-67 affords Lewis acidity and C Pd offers higher hydrogenation activity relative to solely Pd NPs.
金属纳米粒子(NPs)被 MOFs 稳定后在催化方面非常有前景,然而,将 C 引入 MOFs 中很少被使用,并且在有机合成中也没有关于它们协同催化的报道。在这项工作中,通过一锅法合成了 C@UiO-67,使得 C 以分子形式均匀分布在 UiO-67 上。与 C 配位的 Pd NPs 已成功嵌入到骨架中。所得到的多功能 C@Pd@UiO-67 催化剂在温和条件下的级联反应中表现出显著的协同催化活性,其中 UiO-67 提供路易斯酸度,而 C@Pd 相对于单独的 Pd NPs 提供更高的加氢活性。
