“…It should be noted that the potential of active iron-containing components in the catalytic processes discussed in this study is still little studied. However, there have been some reported results dealing with the promoting action of iron on active nickel and cobalt-active components [ 8 , 10 , 57 , 58 , 59 , 60 ].…”

“…Ammonia borane (NH 3 BH 3 , AB) is an extensively studied hydride and dozens of review articles have already appeared discussing the results of these studies [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 ]. The high hydrogen content of this hydride (19.6 wt%) allows it to be applied in a variety of fields: as hydrogen storage systems to generate hydrogen for the needs of hydrogen economy [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 ], as a component of fuels [ 11 , 12 ], as a reducing agent in fine organic synthesis [ 13 ] and in the synthesis of metallic nanoparticles [ 14 , 15 ].…”

“…This process is traditionally carried out in an excess of water at room temperature in the presence of various catalysts [ 8 , 9 , 10 , 18 , 19 ]. Because of the high content of water, this process has a low value of gravimetric hydrogen density (GHD < 1 wt%), which is calculated using the ratio of the mass of released hydrogen to the total mass of all reactants and components of the hydrogen-generating system.…”

Catalytic Behavior of Iron-Containing Cubic Spinel in the Hydrolysis and Hydrothermolysis of Ammonia Borane

The paper presents a comparative study of the activity of magnetite (Fe3O4) and copper and cobalt ferrites with the structure of a cubic spinel synthesized by combustion of glycine-nitrate precursors in the reactions of ammonia borane (NH3BH3) hydrolysis and hydrothermolysis. It was shown that the use of copper ferrite in the studied reactions of NH3BH3 dehydrogenation has the advantages of a high catalytic activity and the absence of an induction period in the H2 generation curve due to the activating action of copper on the reduction of iron. Two methods have been proposed to improve catalytic activity of Fe3O4-based systems: (1) replacement of a portion of Fe2+ cations in the spinel by active cations including Cu2+ and (2) preparation of highly dispersed multiphase oxide systems, involving oxide of copper.

“…Non‐redox ester hydrolysis is assisted by redox NADH. In nanomaterial‐based catalytic reactions, ammonia‐borane (H 3 N−BH 3 , AB) can be used as a mild reducing agent that is stable in O 2 ‐containing aqueous solutions [19, 20] . The catalytic reduction of nitro and nitroso groups that takes place in the presence of DT‐D and NADH [21] is also obtained with metal nanoparticles and AB [22] .…”

Metal nanoparticle surfaces are used for peroxidase‐ and oxidase‐like nanozymes but not for esterase‐like nanozymes. It is challenging to obtain rapid catalytic hydrolysis on a metal surface and even more so without a catalytically labile substrate. Here, we report that metal nanoparticle surfaces rapidly catalyze non‐redox ester hydrolysis in the presence of redox H3N−BH3 (AB). Metal hydrides are readily generated on a Pt nanoparticle (PtNP) from AB, and as a result the PtNP becomes electron‐rich, which might assist nucleophilic attack of H2O on the carbonyl group of an ester. The nanozyme system based on PtNP, AB, and 4‐aminonaphthalene‐1‐yl acetate provides an electrochemical signal‐to‐background ratio much higher than natural enzymes, due to the rapid ester hydrolysis and redox cycling involving the hydrolysis product. The nanozyme system is applied in a sensitive electrochemical immunosensor for thyroid‐stimulating hormone detection. The calculated detection limit is approximately 0.3 pg mL−1, which indicates the high sensitivity of the immunosensor using the PtNP nanozyme.

“…[5] Ammonia borane (AB) is considered to be the most potential hydrogen storage material because of high hydrogen storage capacity density, [6] safe and stable at room temperature. [7] Ammonia borane can be hydrolyzed and dehydrogenated at room temperature, which is the most convenient hydrogen production method, [8] but due to its slow reaction kinetics, it is necessary to improve the hydrogen production efficiency under the action of a catalyst.…”

Chemical hydrogen storage ammonia borane has attracted extensive attention as a method of efficient utilization of hydrogen energy. The high-efficiency catalysts are the main factor restricting the hydrogen production of ammonia borane. In this paper, the synergistic effect of Co and CoO x supported on graphene (named CoÀ CoO x @GO-II) promotes the efficient hydrogen production of ammonia borane, and its catalytic hydrogen production rate can reach 5813 mL min À 1 g Co À 1 at 298 K, the corresponding TOF is 15.33 min À 1. After five stability tests, CoÀ CoO x @GO-II maintained 65% of its original catalytic performance. The synergy of metal and metal oxide and the defects in the atomic arrangement ensure the catalytic activity, the large specific surface area of graphene ensures the dispersion and fixation. This strategy may provide a possibility to design highperformance transition metal catalysts.
