Renewable Nanocatalyst Based on Palladium Nanoparticles Decorated on the Functionalized Metal–Organic Framework for Synthesis of Biaryl Derivatives

ABSTRACT The unique postsynthetic functionalization characteristic of metal–organic frameworks (MOF), especially those that possess a free ‐NH 2 group, encourages researchers to design nanocatalysts based on MOF with crystalline architecture. The present work reports a new nanocatalyst of UiO‐66‐NH‐Glu‐Mla@Pd, focusing on its design, synthesis, functionalization, and application in the Suzuki coupling reaction. UiO‐66‐NH 2 MOF was successfully synthesized via a solvothermal method and then functionalized with organic reagents of glutaraldehyde (Glu) and melamine (Mla) using the cocondensation and postsynthesis grafting strategies. Finally, the UiO‐66‐NH‐Glu‐Mla was decorated by palladium nanoparticles to generate UiO‐66‐NH‐Glu‐Mla@Pd. These modifications turn a low‐active MOF into an ideal nanocatalyst with high catalytic activity in the Suzuki reaction. The results showed that the efficiency and durability of structure UiO‐66‐NH‐Glu‐Mla@Pd was still high after at least six consecutive uses.
