To conclude this section, it is necessary to state that experimental hydrogen adsorption studies on zeolites at room temperature are scarce. It has been reported that zeolites can store only very small amounts of hydrogen (<0.5 wt % at 60 bar) at room temperature [151]. In this regard, LSX zeolites, as well, fully exchanged with alkali-metal cations, that is, Li+, Na+, and K+, to get samples Li-LSX, Na-LSX, and K-LSX, were tested for their hydrogen storage capacities at 298 K and 10 MPa, and the measured H2 capacity was 0.6 wt % [38],... 

IINS spectroscopy is an important tool for development of understanding of the interactions between the substrate and the adsorbate in hydrogen-storage materials. In addition to carbon nanotubes 17a,b,c), activated carbon 17d), and several other materials are being actively investigated. These include metal organic framework (MOF) compounds 18b,c), zeolites 18d), and metal phosphates 18e). 

Other industrially applied materials that might be used as a support in hydrogen storage are zeolites and alumina. Zeolites are crystalline aluminosilicates with the... 

To conclude this review, I highlight three topics within heterogeneous catalysis for which DFT-based calculations appear poised to allow rapid progress in the near future, the development of catalysts for use in reversible hydrogen storage, electrocatalysis for fuel cell applications, and catalysis in zeolites.

Very importantly, molecular hydrogen has been observed to bind to porous materials such as zeolites and MOF complexes at low temperatures, and in some cases even at room temperature. The applications here for reversible hydrogen storage...
