Hydrogen Storage in Chabazite Zeolite Frameworks.

Abstract

Sorption G 6000Hydrogen Storage in Chabazite Zeolite Frameworks. -As revealed by volumetric H2 uptake measurements and transmission IR experiments of H2 adsorption, proton exchanged chabazitic frameworks represent, among zeolites, the most efficient materials for hydrogen storage. Within the series of the considered materials, H-SSZ-13 exhibits the best behavior in terms of hydrogen uptake. A proper balance between available space (volume accessible to hydrogen), high contact surface, and specific interaction with strong and isolated polarizing centers are the necessary characteristics required to design better materials for molecular H2 storage. -(REGLI, L.; ZECCHINA*, A.; VITILLO, J.

Adsorption of hydrogen in nickel and rhodium exchanged zeolite X

“…A general chemical formula of zeolites is represented as Recent studies have shown that zeolites can be potential materials for reversible hydrogen storage [6][7][8][9][10][11][12][13][14][15]. Du and Wu reported hydrogen adsorption capacity of 2.55 wt% for NaX at 77 K and 70 bar pressure [7].…”

Hydrogen Storage for Energy Application

“…Also at cryogenic temperatures and 15 bar gravimetric storage capacities of 2.19 wt% was reported for Ca exchanged X zeolite [32]. However, hydrogen adsorption on zeolites at room temperature and 60 bar was reported less than 0.5 wt% [34,40].…”

“…However, hydrogen adsorption on zeolites at room temperature and 60 bar was reported less than 0.5 wt% [34,40]. It was shown that the amount of hydrogen adsorbed on zeolites depended on the framework structure, composition, and acid-base nature of the zeolites [32]. …”

“…Zeolites are prominent candidates for a hydrogen storage medium, due to their structural and high thermal stability, large internal surface area, low cost and adjustable composition [32].…”

A Review on the Production and Purification of Biomass-Derived Hydrogen Using Emerging Membrane Technologies

“…In addition, zeolite is a promising adsorbentand has great potential for hydrogen storage, etc. [99,100]. Zeolite is recognized as an ideal membrane material for gas separation because some zeolites have the unique pore aperture sizes (0.3-1.3 nm) that are comparable to the scale of gas molecules [101,102].…”
