Metal organic frameworks (MOFs) are presently under substantial investigation due to their attractive properties and high potential as a new class of porous materials for hydrogen storage. From the unique structure design, MOFs with the combination of metal oxide clusters and organic linkers present great flexibility and porosity. Hydrogen is forecast to be a main source of clean energy recently. The safety and effective hydrogen storage would be important and practical problems. Therefore, the synthesis, characterization, and hydrogen storage capacity of MOFs structure porous materials were investigated. Experimentally, the dihydrogen adsorption isothermal of copper-based MOFs (HKUST-1) measured at 298 K up to the pressures of 1-30 atm, have been examined for corrections with their structural features. These materials display approximately type I isotherms with no hysteresis, and saturation were nor reached for HKUST-1 under theses conditions. The H2 storage capacity of HKUST-1 ranged from 0.9-1.2 wt% at 298 K and 5-30 atm. In addition, the reaction mechanisms, fine structures, surface properties of MOFs were further identified by FE-SEM/EDS, XRD, XANES/EXAFS and TGA/MS techniques. Charge transfer between linker and vertex, as well as surface area, appear to dominate the sorption behaviour, over that of linker length in HKUST-1 MOFs materials.
