Abstract Highly dispersed palladium nanoparticles (Pd NPs) encapsulated in the mesoporous cages of the metal–organic framework (MOF) MIL-101 (Cr) have been prepared by using the wetness impregnation method. The Pd NPs were characterized by powder X-ray diffraction (PXRD), N 2 adsorption, transmission electron microscopy, inductively coupled plasma atomic emission spectroscopy (ICP-AES), and X-ray ...
