A bi-organic-ligand type of Zn₂(bdc)₂dabco MOFs was synthesized and characterized in the present work. The catalytic properties of Pt/AC and Pd/AC were studied for hydrogen spillover in Zn₂(bdc)₂dabco modified by 5.0wt.% of catalyst. The hydrogen adsorption capacity of modified Zn₂(bdc)₂dabco was significantly enhanced up to 3.35wt.% by using the secondary spillover with carbon bridges measured at 1.5bar and 77K. Moreover, the prepared MOFs were also identified using FE-SEM, HR-TEM, XRD, XANES/EXAFS, and BET N₂ adsorption isotherms techniques.
