چکیده
Metal-organic frameworks (MOFs) are a new class of porous materials, which are formed from metal ions or metal clusters as nodes and organic ligands as linkers [1]. MOFs have received much attention because of their special properties such as ultrahigh porosity, tunable cavity sizes, various topologies and high surface area as well as the possibility of functionalization with different odifier [2]. MOFs have been studied for the various applications, including gas storage, separation, catalysis, and drug delivery [3]. Due to exceptional thermal, chemical, and mechanical stability as well as large specific surface of UIO-66-NH2 area, in this project, nonporous MOF was prepared using organic ligand of 2- amino-1, 4-benzenedicarboxilic acid (NH2-BDC) and zirconium (IV) chloride. Then, during the process of PSM, MOF was modified by glyoxal due to the formation of N, N-chelating ligand which is suitable for is coordination of the metal ions. Then Pd (II) ions were anchored onto the surface of modified nanoporous UIO-66-NH2 and then reduced Pd0 NPs. The formation of Pd NPs supported on MOF was confirmed by transmission electron microscopy (TEM) and EDX-MAP. As well, according to the inductive couple plasma atomic emission spectroscopy (ICP), around 2.98 w% of Pd NPs was present in the modified MOF. Finally, we studied the application UIO-66-NH2-Gl@PdNPs as catalyst in three- component coupling (A3) reactions for synthesis of propargylamines (Fig1).کليدواژه ها
