“…Liquid hydrides have long been considered for vehicular applications given the practicality of transport within the existing infrastructure [235,236]. An early approach utilized in Chrysler's ''Natrium'' relied on the exothermic release of H 2 from aqueous solutions of NaBH 4 .…”

The research on complex hydrides for hydrogen storage was initiated by the discovery of Ti as a hydrogen sorption catalyst in NaAlH 4 by Boris Bogdanovic in 1996. A large number of new complex hydride materials in various forms and combinations have been synthesized and characterized, and the knowledge regarding the properties of complex hydrides and the synthesis methods has grown enormously since then. A significant portion of the research groups active in the field of complex hydrides is collaborators in the International Energy Agreement Task 32. This paper reports about the important issues in the field of complex hydride research, i.e. the synthesis of borohydrides, the thermodynamics of complex hydrides, the effects of size and confinement, the hydrogen sorption mechanism and the complex hydride composites as well as the properties of liquid complex hydrides. This paper is the result of the collaboration of several groups and is an excellent summary of the recent achievements.

“…1 -4 Decalins have also found numerous applications; recent ones include their use in the production of nanomaterials 5 and in hydrogen storage in fuel cells. 6,7 The decalins also play an important negative role as pollutants and environmental contaminants. 8 Therefore, spectral characterization of these molecules is of interest and significance (for instance, NMR spectra of substituted trans-and cisdecalins were recently used to prove the structure of a natural compound).…”

1H and13C NMR chemical shifts and spin-spin coupling constants intrans- andcis-decalins

The NMR parameters characterizing the spectra of trans- and cis-decalins were determined from theoretical calculations and experimental spectra. The calculated values of the shielding constants are in good agreement with the measured chemical shifts, with a small but noticeable difference in accuracy for the bridgehead atoms. Of all the spin-spin coupling constants, only most of (1)J(C,C) and (1)J(C,H) values could be extracted from the spectra, and the corresponding computed values are in good agreement with experiment. It appears that the applied density functional theory (DFT) approach overestimates slightly the J(C,C) coupling and underestimates the differences between one-bond (1)J(C,H) coupling constants. For all these constants [J(C,C), J(C,H) and J(H,H)] through one to three bonds, which could not be obtained experimentally, the predicted values are in good agreement with the general rules relating spin-spin coupling to the number and spatial arrangement of the intervening bonds.

“…As a matter of fact, existing gas stations or tank lorries are available for using either decalin or naphthalene oil [16,17] (vide post). All of these advantages for storage and transportation of hydrogen suggest to us that decalin is suitable as one of the organic chemical hydrides for www.elsevier.com/locate/apcata Applied Catalysis A: General 292 (2005) 90-96 supplying hydrogen to fuel cells loaded in automobiles [5,8,12,13].…”

“…In order to evolve hydrogen rapidly from tetralin at mild temperature ranges, ''superheated liquid-film-type catalysis'' [2][3][4][5][6][7][8][9][10][11][12][13] with carbon-supported metal nano-particles was attempted to tetralin dehydrogenation with comparing dehydrogenation catalysis for decalin under the same conditions. In addition, the feasibilities of carbon-supported nickel-based catalysts as the alternative of platinum were examined in the present study.…”
