通过双溶剂法结合光还原工艺制备了封装在 NH2-Uio-66(Zr) 笼内的小于 1.2 nm 的活性 Pd 纳米团簇 (Pd@NH2-Uio-66(Zr))。由于光激发的NH2-Uio-66(Zr)的电子有效转移到受限的Pd纳米团簇以及大量催化活性Pd物质的存在，所得的Pd@NH2-Uio-66(Zr)在可见光照射下表现出优异的Suzuki偶联反应性能。 MOF基光催化与金属@ MOFs上的金属基催化的成功耦合有望为开发用于各种光诱导有机转化的活性催化剂带来巨大的机会，这归因于多样化的MOF结构及其可调特性。
Active Pd nanoclusters smaller than 1.2 nm encapsulated inside the cage of NH2-Uio-66(Zr) (Pd@NH2-Uio-66(Zr)) were prepared via a double-solvent approach combined with a photoreduction process. The resultant Pd@NH2-Uio-66(Zr) showed excellent performance for Suzuki coupling reaction under visible-light irradiations as a result of the efficient electron transfer from the light-excited NH2-Uio-66(Zr) to the confined Pd nanoclusters and the presence of large amounts of catalytic active Pd species. The successful coupling of MOF-based photocatalysis with metal-based catalysis over metal@ MOFs is expected to bring about vast opportunities for developing active catalysts for a variety of light-induced organic transformations attributed to the diversified MOF structures and their tunable characteristics.
