“…Catalysts in various forms have been investigated. Metal organic framework-supported metal nanoparticles [97][98][99], silica-supported bi-/ter-nary composites [100][101][102][103], graphene-containing catalytic materials [104][105][106][107], nitride as active phase supports [108][109][110], cobalt-based alloys and catalysts [111][112][113][114][115], nickel-based systems [116][117][118], supported ruthenium nanostructures [119][120][121][122] and palladium-based materials [123][124][125][126] are examples among the catalysts reported within the last three years. Such efforts have allowed the development of many active heterogeneous catalysts like the rhodium nanoparticles supported over cobalt (II, III) oxide, which attained a turnover frequency of 1800 min −1 and a total of 1.02 × 10 6 turnovers for hydrogen release at 25 • C [127].…”

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.

“…Due to the environmental issues induced by the utilization of fossil fuels, it has been very vital to develop safe and efficient ways to store energy in which hydrogen is appeared to be the best candidate over the last decades. However, accomplishment of the safe and effective hydrogen storage remains as the most challenging hurdle towards the implementation of practical applications [1,2] . Chemical hydrogen storage in which the hydrogen is bonded covalently is an important option for this purpose and hydrogen can be released when needed during the on‐board applications by different means including hydrolysis, thermolysis, dehydrogenation, and alcoholysis.…”

Here, the first ever preparation of some series of nanoceria‐supported Ru‐based nanoparticles with different compositions (RuxM100‐x@NC, M: Co, Ni, Pd) and their use as highly active catalysts to liberate hydrogen gas from hydrolysis of ethane 1,2‐diamine borane (EDAB) is reported. For the preparation of totally fifteen RuxM100‐x@NC nanoparticles with different compositions, the related metal cations are first supported on nanoceria surfaces by wet impregnation method in aqueous solution. Then, Ru3+‐M2+‐exchanged nanoceria samples are synchronously reduced during hydrolysis reaction of EDAB to form corresponding RuxM100x@NC nanoparticles meanwhile the formed nanoparticles catalyze the same reaction. RuxM100x@NC nanoparticles are identified by inductively coupled plasma‐optical emission spectroscopy (ICP‐OES), powder X‐ray diffraction (PXRD), transmission electron microscopy (TEM), X‐ray photoelectron spectroscopy (XPS), and BET surface area techniques. They provide quiet high catalytic activities in the hydrolysis reaction of EDAB. Among them, Ru20Pd80@NC nanoparticles are by far the best one up to date with a TOF value of 608.49 min−1 at 25 °C.

“…[15], SiO2 [15,18,19], graphene [20,21], graphitic carbon nitride [22,23], and other support materials [24][25][26][27] were the most efficient catalysts for the HAB. To decrease the cost of these catalysts yet maintaining their catalytic activity, the bimetallic nanocatalysts composed of nonnoble metals (i.e., Fe, Co, Ni, and Cu) and noble metals have been reported to be highly efficient catalysts in hydrogen generation from the HAB [28][29][30]. However, the ultimate target for the practical applications is the development of efficient noble metal-free nanocatalysts for the AB hydrolysis [31][32][33].…”

We reported a facile one-pot synthesis of bimetallic CoCu nanoparticles (NPs) anchored on graphene hydrogel (GH-CoCu) as catalysts in hydrogen generation from the hydrolysis of ammonia borane (HAB). The presented novel one-pot method composed of the reduction of the mixture of graphene oxide, cobalt(II), and copper(II) acetate tetrahydrates by aqueous ethylene glycol solution in a teflon-coated stainless-steel reactor at 180 o C. The structure of the yielded GH-CoCu nanocatalysts were characterized by TEM, SEM, XRD, XPS, and ICP-MS. This is the first example of both the synthesis of bimetallic CoCu NPs anchored on GH and the testing of a hydrothermally prepared noble metal free GH-bimetallic nanocomposites as catalysts for the HAB. The presented in situ synthesis protocol allowed us to prepare different metal compositions and investigating their catalysis in the AB hydrolysis, where the best catalytic activity was accomplished by the GH-Co33Cu67 nanocatalysts. The obtained GH-CoCu nanocatalysts exhibited a remarkable catalytic performance in the HAB by providing the highest hydrogen generation rate of 1015.809 ml H2 gcatalyst -1 min -1 at room temperature. This study has a potential to pave a way for the development of other GH-based bimetallic nanocatalysts that could be used in different applications.
