“…The onset dehydrogenation temperature of NaAlH 4 with 10 wt % C@TiO 2 /Ti 3 C 2 was found to be reduced by 70 °C compared to the pure NaAlH 4 . About 4.0 wt % hydrogen was released in 13 min at 140 °C during the dehydrogenation processes of NaAlH 4 –C@TiO 2 /Ti 3 C 2 composites . It was found that the onset dehydrogenation temperature of NaAlH 4 with 5 wt % MnTiO 3 nanoparticles was only 70.6 °C.…”

Hydrogen is one of the cleanest energies with potential to have zero carbon emission. Hydrogen storage is a challenging phase for the hydrogen energy application. The safety, cost, and transportation of compressed and liquified hydrogen hinder the widespread application of hydrogen energy. Chemical absorption of hydrogen in solid hydrogen storage materials is a promising hydrogen storage method due to its high storage and transportation performance. Hydrogen storage density, dehydrogenation temperature, and dehydrogenation dynamics are the main challenges for the hydrogen storage materials. The ultimate goal of the system gravimetric capacity was set by the Department of Energy to be 6.5 wt % with a working temperature from −40 to 60 °C. The theoretical densities of most present hydrogen storage materials are even lower than 6.5 wt %, which make it impossible to reach the system gravimetric capacity goal. Only hydrogen storage materials with high theoretical density (≥10 wt %) with further modification have the possibility to reach the goal. However, most of the reviews focus on the research progress of general hydrogen storage materials investigated, many of which have low density. Hydrogen storage materials with high theoretical density including metal borohydrides, metal alanates, ammonia borane, metal amides, and amine metal borohydrides have been reviewed in this article. The pyrolysis and hydrogen absorption conditions of the hydrogen storage materials have been summarized, especially the improvements of the hydrogen storage materials. Furthermore, the challenges of the hydrogen storage materials have been pointed out. Potential hydrogen storage materials and possible modification methods have also been presented and discussed.

“…Ongoing recent trends in developing novel systems for energy storage have incorporated MXene materials with a 2D structure, as promising hydride hosts [94,156,[176][177][178][179][180][181][182][183][184][185][186][187][188][189][190][191][192][193][194]. While only few examples are currently available, it is foreseeable that MXenes will grow to become a mainstream storage matrix for nanoconfined hydride-based materials (Table 7).…”

“…The overall enhancement of kinetic and thermodynamic parameters can be tuned by utilization of catalysts. This is usually implemented to improve behavior of systems that already show promising results including recyclability (Table 9) [19,20,34,43,57,65,68,77,82,92,102,108,113,118,120,125,131,132,134,136,139,143,147,158,160,[166][167][168]172,[183][184][185][186][187][188][189][190][191][192]194,[196][197][198][199][200][201][202][203]…”

Hydrogen is the ultimate vector for a carbon-free, sustainable green-energy. While being the most promising candidate to serve this purpose, hydrogen inherits a series of characteristics making it particularly difficult to handle, store, transport and use in a safe manner. The researchers’ attention has thus shifted to storing hydrogen in its more manageable forms: the light metal hydrides and related derivatives (ammonia-borane, tetrahydridoborates/borohydrides, tetrahydridoaluminates/alanates or reactive hydride composites). Even then, the thermodynamic and kinetic behavior faces either too high energy barriers or sluggish kinetics (or both), and an efficient tool to overcome these issues is through nanoconfinement. Nanoconfined energy storage materials are the current state-of-the-art approach regarding hydrogen storage field, and the current review aims to summarize the most recent progress in this intriguing field. The latest reviews concerning H2 production and storage are discussed, and the shift from bulk to nanomaterials is described in the context of physical and chemical aspects of nanoconfinement effects in the obtained nanocomposites. The types of hosts used for hydrogen materials are divided in classes of substances, the mean of hydride inclusion in said hosts and the classes of hydrogen storage materials are presented with their most recent trends and future prospects.

“…To overcome these issues, a variety of Tiand Ce-based catalytic additives have been used to improve the hydrogen storage performance of NaAlH 4 . [4][5][6][7][8] Rapid hydrogen desorption at temperatures below 100 C and superior cycling properties have been demonstrated using high-performance transition metal-carbon composite catalysts. 9,10 In addition to such transition metal-based catalysts, nanoconnement of metal hydrides into a variety of nanoporous scaffolds has been employed.…”
