dc.description | The non-availability of an appropriate storage medium for hydrogen is probably the main challenge for a hydrogen-based energetic technology development. The hydrogen oxidation produces 572 kJ/mol (three times the energy obtained from gasoline), with water as by-product. However H2 has an extremely low critical temperature (32.9 K) to be handled in liquid phase. The option of high pressure vessel also appears to be impractical, for a pressure of 345 atm, a storage density of 15 g/L is obtained, well below the value of 71 g/L corresponding to the liquid state. From these facts, the storage in porous solids is being evaluated due to its high reversibility. Among the considered materials in that sense, Prussian blue (PB) analogues have been considered in that sense due to the availability of metal center with open coordination sites on the cavities surface [1, 2]. These sites are available for a specific interaction with the hydrogen molecule [3, 4]. In this contribution we are reporting the behavior of PB analogues on heating for the water removal from the porous framework and then during their cooling for the hydrogen storage ability evaluation. The changes observed in the materials electronic structure on their dehydration also shed ligth on the possibility of magnetic properties modulation in porous solids through adsorbed species. | - |
