Sorption Characteristics

In the field of energy storage, recently investigated nanocomposites show promise in terms of high hydrogen uptake and release with enhancement in the reaction kinetics. Among several, carbonaceous nanovariants like carbon nanotubes (CNTs), fullerenes, and graphitic nanofibers reveal reversible hydrogen sorption characteristics at 77 K, due to their van der Waals interaction. The spillover mechanism combining Pd nanoparticles on the host metal-organic framework (MOF) show room temperature uptake of hydrogen. Metal or complex hydrides either in the nanocomposite form and its subset, nanocatalyst dispersed alloy phases illustrate the concept of nanoengineering and nanoconfinement of particles with tailor-made properties for reversible hydrogen storage. Another class of materials comprising polymeric nanostructures such as conducting polyaniline and their functionalized nanocomposites are versatile hydrogen storage materials because of their unique size, high specific surface-area, pore-volume, and bulk properties. The salient features of nanocomposite materials for reversible hydrogen storage are reviewed and discussed.

Gravimetric Adsorption

In this paper, we report the synthesis of polymer coated palladium ( Pd ) nanoparticles through a single stage reduction of Pd 2+ ions by ethylene glycol. Polyvinyl pyrrolidone (PVP, MW 25,000) is used as a stabilizer. Self-assembled Pd nanoparticles (10–40 nm) were used in hydrogen adsorption studies. Gravimetric adsorption measurements were carried out in a pressure range of 0–26 bar at 293, 324, 364 and 392 K. Saturation for all isotherms was obtained within a few bars of pressure at all temperatures. Maximum hydrogen storage capacity observed was 0.58 wt.% at 324 K and 20 bar. Net adsorption calculations indicated that required tank volume (for storing a particular amount of hydrogen) can be significantly reduced by using a tank filled with Pd nanoparticle.

Pore Properties

Natural diatomite, subjected to different modifications, is investigated for hydrogen adsorption capacities at room temperature. An effective metal-modified strategy is developed to disperse platinum ( Pt ) and palladium ( Pd ) nanoparticles on the surface of diatomite. Hydrogen adsorption capacity of pristine diatomite (diatomite) is 0.463 wt.% at 2.63 MPa and 298 K, among the highest of the known sorbents, while that of acid-thermally activated diatomite (A-diatomite) could reach up to 0.833 wt.% due to the appropriate pore properties by activation. By incorporation with a small amount of Pt and Pd (~0.5 wt.%), hydrogen adsorption capacities are enhanced to 0.696 wt.% and 0.980 wt.%, respectively, indicating that activated diatomite shows interesting application in the field of hydrogen storage at room temperature.
