Advanced Synthesis of Porous Nanocomposite MOF/Gold-Nanoparticles-Decorated ATPMS/Polydopamine as Novel EfficientCatalyst in O-Arylation Reactions

This study aims to synthesize a highly efficient and reusable catalyst through a step-by-step post-synthesismodification of UiO-۶۶-NH۲ metal-organic framework (MOF) with Aminopropyltrimethoxysilane/ Polydopamine andhired as support for the preparation of UiO-۶۶-NH۲ / APTMS@ Polydopamine/Au-NPs. This work is motivated toidentify newly synthesized MOF nano-catalyst via metal-organic frameworks UiO-۶۶-Type with amino group as anefficient MOF functionalized with APTMS/Polydopamine via decoration of palladium - nanoparticles. In order toprepare a highly efficient catalyst UiO-۶۶-NH۲ @ APTMS@ Polydopamine @ Au-NPs as a heterogeneous catalyst forapplying to O-arylation reactions which have been investigated. The proposed catalyst represented superior catalyticperformance for promoting the O-arylation reactions in green aquatic media. The results of productivity catalyst areaccomplished in excellent yields under mild conditions which is a proof of superior activity heterogeneous catalystcontaining Au-nanoparticles. In addition, the proposed catalyst represented excellent reusability with no remarkableloss in activity up ۷ sequential runs. In addition, the characterization of the prepared nano‑ materials were performedusing different analyses such as FTIR, XRD, SEM, EDS, TEM, and BET and the results proved the successfulsynthesize of UiO‑ ۶۶‑ NH۲ / Gold-nanocomposite.
