This perspective describes the recent discovery and investigation of homopolar dihydrogen bonding, and focuses on the identification and characterisation of hydride-hydride interactions in compounds of the main group elements. A highlight of this programme has been an appreciation of the important role played by this interaction in the structural and thermochemical properties of these materials, and in the mechanisms through which they release hydrogen. A fuller understanding of this new class of H∙∙∙H interactions has also allowed us to explore their role in the supramolecular chemistry of hydrogen-rich compounds.

“…However, a catalyst can significantly enhance kinetics, heighten the degree of stability, and/or possess more favourable thermodynamic properties [6]. Meanwhile, the reactive hydride composites (RHCs) method is quite a different approach that aims at modifying the thermodynamics and kinetics of the hydrogen sorption reaction by mixing two or more hydrides [7e14].…”

“…[10] Since their discovery,alarge number of complexh ydrides have been explored, and some of them have been found to be thermodynamicallyf avorable for on-boarda pplications. [5,11] In 2006, Bogdanović et al demonstrated that compounds of some less-common metals could also be used as highly efficientd opants for NaAlH 4 . [12] In particular, recent results show that dehydrogenated nanocrystalline TiO 2 @Cdoped NaAlH 4 can absorb 4.5 wt %H 2 within 12 min at 80 8Cu nder 100 bar (1 bar = 0.1 MPa) of hydrogen pressure.…”

Development of Catalyst‐Enhanced Sodium Alanate as an Advanced Hydrogen‐Storage Material for Mobile Applications

As a prototypical high‐capacity complex hydride, sodium alanate (NaAlH4) has attracted significant attention because of its favorable thermodynamics and the potential low cost of its raw materials (NaH and Al). However, a high desorption temperature and slow kinetics preclude its practical use, particularly in mobile applications. The introduction of appropriate catalysts has been demonstrated to reduce the operating temperature and to improve the reversibility of hydrogen storage in NaAlH4 effectively. In this Review, we survey the development of various catalytic additives and their effects on the hydrogen‐storage behavior of NaAlH4. First, the basic physical and chemical characteristics of NaAlH4 and its catalyst‐doping methods are briefly summarized. Then, the catalytically enhanced hydrogen‐storage properties and the corresponding mechanistic understanding are highlighted. Finally, the remaining challenges and the directions of future research efforts are discussed.
