Stabilization of Pd NPs over the surface of -cyclodextrin incorporated UiO-66-NH₂ for the C-C coupling reaction

Here, we prepared UiO-66-NH2 and employed a post-synthesis modification method for its functionalization with a beta-cyclodextrin (beta-CD) organic compound. The resulting composite was employed as a support for the heterogenization of the Pd NPs. Various techniques, including FT-IR, XRD, SEM, TEM, EDS, and elemental mapping, were used to characterize UiO-66-NH2@beta-CD/Pd-NPs, indicating its successful preparation. Three C-C coupling reactions, including the Suzuki, Heck, and Sonogashira coupling reactions, were promoted using the produced catalyst. As a result of the PSM, the proposed catalyst displays improved catalytic performance. In addition, the suggested catalyst was highly recyclable up to 6 times.
