摘要

了解串联反应体系中的协同作用仍然是催化领域的一个令人着迷的追求。在本研究中，我们以金属有机框架（MOFs）为基础，合成了一种类似三明治的纳米结构催化剂 UiO-66-NH2@(PdAu)@MOF-808。PdAu 纳米粒子可以激活 H2，而 MOF-808 既是活性酸性位点，又是封装体，即 "活性铠甲"。得益于 MOF-808 和 PdAu 纳米粒子的协同作用，所开发的催化剂在温和条件下（30 °C、1 atm H2）进行还原胺化反应时表现出卓越的性能。

Unveiling synergistic catalysis in reductive amination through a UiO-66-NH2@(PdAu)@MOF-808 sandwich nanostructure

Understanding the synergistic interplay within tandem reaction systems remains a captivating pursuit in catalysis. In this study, we synthesize a sandwich-like nanostructured catalyst, UiO-66-NH₂@(PdAu)@MOF-808, based on metal organic frameworks (MOFs). The PdAu nanoparticles can activate H₂, and MOF-808 acts as both the active acidic site and encapsulator, namely “active armor”. Benefiting from the synergy of MOF-808 and PdAu NPs, the developed catalyst shows outstanding performance for reductive amination under mild conditions (30 °C, 1 atm H₂).
