“…It goes beyond the scope of the present work to survey all of the mono-and multi-metallic amidoboranes reported so far. All have been discussed at length in a series of reviews [299][300][301][302][303], and hereafter only the monometallic alkali and alkaline-earth amidoboranes are tackled.…”

“…It is worth briefly mentioning that there are alternative routes for preparing alkali amidoboranes, as surveyed in details in refs. [299][300][301][302][303]. Lithium amidoborane is a crystalline solid, having two allotropes, the α and the β phases; both crystallize in the orthorhombic space group Pbca, but the unit cell of the β phase is twice that of the α phase [305].…”

Ammonia borane H3N−BH3 (AB) was re-discovered, in the 2000s, to play an important role in the developing hydrogen economy, but it has seemingly failed; at best it has lagged behind. The present review aims at analyzing, in the context of more than 300 articles, the reasons why AB gives a sense that it has failed as an anodic fuel, a liquid-state hydrogen carrier and a solid hydrogen carrier. The key issues AB faces and the key challenges ahead it has to address (i.e., those hindering its technological deployment) have been identified and itemized. The reality is that preventable errors have been made. First, some critical issues have been underestimated and thereby understudied, whereas others have been disproportionally considered. Second, the potential of AB has been overestimated, and there has been an undoubted lack of realistic and practical vision of it. Third, the competition in the field is severe, with more promising and cheaper hydrides in front of AB. Fourth, AB has been confined to lab benches, and consequently its technological readiness level has remained low. This is discussed in detail herein.

“…The AB@rGO nanocomposite released H 2 as low as 70 • C [137]. A closely-related lithiated species of AB, namely lithium amidoborane LiNH 2 BH 3 , has been utilized to produce LiNH 2 BH 3 /G nanocomposites that released 10.9 wt.% H 2 without (BN) x byproducts such as borazine [138].…”

Energy production, distribution, and storage remain paramount to a variety of applications that reflect on our daily lives, from renewable energy systems, to electric vehicles and consumer electronics. Hydrogen is the sole element promising high energy, emission-free, and sustainable energy, and metal hydrides in particular have been investigated as promising materials for this purpose. While offering the highest gravimetric and volumetric hydrogen storage capacity of all known materials, metal hydrides are plagued by some serious deficiencies, such as poor kinetics, high activation energies that lead to high operating temperatures, poor recyclability, and/or stability, while environmental considerations related to the treatment of end-of-life fuel disposal are also of concern. A strategy to overcome these limitations is offered by nanotechnology, namely embedding reactive hydride compounds in nanosized supports such as graphene. Graphene is a 2D carbon material featuring unique mechanical, thermal, and electronic properties, which all recommend its use as the support for metal hydrides. With its high surface area, excellent mechanical strength, and thermal conductivity parameters, graphene can serve as the support for simple and complex hydrides as well as RHC (reactive hydride composites), producing nanocomposites with very attractive hydrogen storage properties.

“…Fuel cell technologies currently used in automotive applications impose certain requirements on candidate materials for hydrogen storage such as high purity of released hydrogen, favorable kinetics, operation temperature well below 100 °C and ability of spent material regeneration either via on-or off-board procedures. Lithium amidoborane (LiAB), LiNH 2 BH 3 , is regarded as one of the most promising materials for the development of a lightweight storage medium for hydrogen 1 . In general, LiAB is a compound out of a large family of hydrogen-rich Boron-Nitrogen (B-N-H) materials, which number has been growing fast over the last decade 2,3 .…”

In situ high-pressure synchrotron X-ray diffraction, Raman scattering, and complementary first-principles calculations have revealed that structural and spectroscopic properties of lithium amidoborane compound are largely determined by multiple heteropolar dihydrogen bonds. The crystal structure of the compound is stabilized by dimeric complexes, wherein molecular ions bind together by intermolecular dihydrogen bonds of unconventional type. This strong intermolecular coupling determines stable character of the crystal structure in the pressure range up to ~ 30 GPa and is spectroscopically manifested by pronounced changes related to molecular vibrations of the amino group: the splitting of stretching modes, the anomalous behavior of wagging modes as well as Fermi resonance due to vibrational coupling of bending and stretching modes, significantly enhanced above 10 GPa. Unconventional nature of dihydrogen bonds is confirmed by the frequency increase, blueshift, of NH stretching modes with pressure. A role of certain hydrogen mediated interactions in the process of dehydrogenation of ammonia borane and its alkali metal derivatives is speculated. Findings presented here call for reconsideration of hydrogen release mechanism from alkali metal ammonia borane derivatives. The work makes significant contribution towards establishing the general theory of ubiquitous and versatile hydrogen mediated interactions.
