Highly dispersed palladium nanoparticles supported on amino functionalized metal-organic frameworks as an efficient and reusable catalyst for Suzuki cross-coupling reaction

•Pd nanoparticles were immobilized on UiO-66-NH2.•A heterogeneous catalyst was prepared.•The catalyst was used for Suzuki–Miyaura coupling reactions.•The catalyst was reusable.

Palladium nanoparticles (Pd NPs) supported on amino functionalized UiO-66-NH2 (UiO = University of Oslo) metal-organic framework was prepared using a direct anionic exchange method followed by chemical reduction with sodium acetate in methanol. This nano palladium containing catalyst was characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), N2 adsorption, inductively coupled plasma atomic emission spectroscopy (ICP-AES), field emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM). The Pd/UiO-66-NH2 catalyst showed excellent activity in Suzuki–Miyaura cross-coupling reaction and reused several times without any appreciable loss of activity even after five consecutive times.
