Abstract
The structures and hydrogen adsorption properties of {Cr3F(H2O)2O[(O2C)-C6H4-(CO2)]3ã»nH2O(nâ¼25)} (MIL-101) and its Pd composites have been investigated by X-ray diffraction (XRD) analysis, transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS), and specific surface area tests (BET). The as-prepared Pd/MIL-101 composites were microporous and maintained three-dimensional topology of MIL-101 before and after Pd loading that existed in the skeleton. A carbon bridge was formed between Pd metal and MIL-101 to improve the hydrogen storage. The loaded Pd reduced the hydrogen absorption enthalpy of MIL-101, and thus improved the storage of hydrogen compared with MIL-101. The diffusion coefficient reached 7.233â¯Ãâ¯10â9 in the Pd/MIL-101 nanocomposites.
