Recently, hydrogen has attracted much attention as a promising energy resource and is expected to be applied to fuel cell systems. We prepared nickel (Ni)-loaded activated carbons (Ni-ACs)/MOF-5 hybrid composites in order to enhance the hydrogen storage capacity of MOF-5 at 298K and 77K. The Ni-ACs/MOF-5 was prepared using a hydrothermal process, which was synthesized with Zn (II) ion as a metal centre and terephthalic acid as organic ligands. The Ni-ACs/MOF-5 formed crystalline structures, measured by XRD. The textural properties of the Ni-ACs/MOF-5 were investigated by N2/77K adsorption isotherm. The hydrogen storage capacity of the Ni-ACs/MOF-5 was investigated by BEL-HP at 298K/10MPa. From the results, we concluded that the Ni-ACs/MOF-5 would be potentially encouraging materials for hydrogen adsorption and storage applications at 298K. |
