Synthesis and characterization of Pd nanoparticles anchored on MIL 101(Cr) as a novel and recyclable catalyst for the Suzuki cross-coupling reactions

Abstract

Metal-organic frameworks (MOFs), specially, MIL-101(Cr) are utilized as a catalyst in plenty of industrial catalyst applications. In this study synthesis and characterization of MIL-101(Cr)-ED-Glu-Pd is reported. First, MIL-101(Cr) was functionalized with ethylenediamine (ED) by the post-synthesis method (PSM), second, palladium nanoparticles were entangled on the surface of MIL-101(Cr) with a novel strategy. The morphology and structure of the synthesized MIL-101(Cr)-ED-Glu-Pd were determined by using of XRD (X‐ray diffraction), FT‐IR (Fourier transform infrared), SEM (Scanning electron microscopy), EDX (Energy dispersive analysis of X‐ray), BET (Brunauer Emmett Teller), XPS (X-ray photoelectron spectroscopy), TGA (Thermogravimetric) and ICP‐MS (Inductively coupled plasma mass spectrometry). We surveyed the action of catalytic of MIL-101(Cr)-ED-Glu-Pd in Suzuki−Miyaura connector reaction between phenylboronic acid with aryl halides (Ar‐X, X = I, Br, Cl, F). Our studies show that this compound can be a suitable catalyst in carbon−carbon cross-coupling reactions because of having some advantages such as short time, high yield, and easy reusability. • Create MIL-101(Cr) with regular and uniform structure • A heterogeneous catalyst was designed by anchored Pd nanoparticles onto MOF by PSM. • Catalytic activity of MIL-101(Cr)-ED-Glu-Pd with aryl fluoride • The terminal nitrogen atoms of ethylenediamine (ED) on grafted MIL-101 were treated with glutaraldehyde (Glu) • Stability of this prepared catalyst after five times reusability
