The core-shell structure and penetrated structure of Pd-modified metal organic frameworks MOF-808 series materials (named as Pd@MOF-808) are successfully synthesized using Zr(IV) as centron ion, trimesic acid as ligand and Pd as modifier by simple solution method. The structure control and properties of Pd@MOF-808 are characterized by XRD, FT-IR, TEM, XPS, UV-Vis, specific surface area measurement, thermogravimetric analysis, photocatalytic hydrogen production and hydrogen storage testing. The results show that the synthesized Pd nanoparticles have been successfully introduced into the cavity and channel of MOF-808, and the structure of Pd@MOF-808 series materials could remain stable at 350 degrees C. Photocatalytic hydrogen production experiments exhibit the highest hydrogen production of Pd@MOF-808-b (236 mu molg(-1)h(-1)). More importantly, the results of the adsorption experiment show that the hydrogen storage capacities of the as-prepared 10 wt% Pd@MOF-808-b could reach 2.61 wt%, 5.04 wt% and 8.20 wt% under 4MPa at 300K, 195K and 77K, respectively. Furthermore, thermodynamic analysis shows that the maximum hydrogen adsorption enthalpy of Pd@MOF-808-b up to -1.378kJmol(-1) indicates excellent potential for hydrogen storage and application.
