Hydrogen Storage and Separation

One of the first MOFs investigated for H storage was the cubic carbox-ylate-based framework MOF-5 or IRMOF-1, IRMOF-6, and IRMOF-8 (Fig. 3.5) [28]. With complete activation, MOF-5 can adsorbs 7.1 wt% H at 77 K and 40 bar and 10.0 wt% at 100 bar. The latter value is corresponding to a record volumetric storage density of 66 g L which is near the density of liquid Hj at 20.4 K and 1 bar [29]. This MOF material is the best cryogenic storage material currently known. In addition, it was demonstrated that Hj can

On the other hand, MOFs are also promising adsorbents for the purification of due to their tunable porous structures. Molecular sieving using MOFs has been used to separate and CH due to their different kinetic diameters

The ability to control hydrogen diffusion in zeolites, through dissociation and recombination rather than thermal activation, may prove crucial in the design of improved hydrogen storage and separation materials.
