Abstract

AbstractWell‐dispersed palladium nanoparticles (Pd NPs) supported on amine‐functionalized, mixed‐linker metal–organic frameworks (MIXMOFs) based on MIL‐53(Al) were prepared by using the ion‐exchange method. Pd NPs were characterized by powder X‐ray diffraction (XRD), N2 adsorption, transmission electron microscopy (TEM), inductively coupled plasma atomic emission spectroscopy (ICP‐AES), and X‐ray photoelectron spectroscopy (XPS). The mean diameter of Pd NPs is approximately 3.2 nm. It was found that the Pd NPs supported on amine‐functionalized MIXMOFs are stable at high temperature. The Pd NPs exhibit efficient catalytic activity for Heck reaction and can be easily recovered and reused.
