Abstract

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. © 2014 Elsevier B.V.
