“…The first synthesis of AB was reported in 1955, and several improved methods have been reported since then [40], [41], [42], [43], [44], [45], [46], [47], [48]. Besides hydrolysis, pyrolysis and alcoholysis can also dehydrogenate AB, however, hydrolysis has the advantages of a lower reaction temperature than pyrolysis and a faster hydrogen release rate than alcoholysis [49], [50], [51], [52], [53], [54], [55], [56], [57], [58].…”

Hydrogen is one of the clean energies that will play an important role in energy selection for the coming low-carbon society. Ammonia borane (NH3BH3, abbreviated hereafter as AB) is considered as a promising hydrogen storage material due to its high hydrogen content (19.6 wt%), stability under ambient conditions (white powder), and favorable properties in dehydrogenation. AB can release hydrogen via pyrolysis, alcoholysis, hydrolysis, etc. Among these, AB hydrolysis is a safe and effective route, as it proceeds under mild conditions in the presence of an appropriate catalyst without the need for additional heat sources. For practical application, it is important to develop an efficient catalyst that further improves the hydrolytic dehydrogenation properties of AB. Many papers and reviews have been published, suggesting the research is at an advanced stage. On the other hand, since new technologies are often patented before they are put into practical use, the status of patent publication is of significant interest. This mini-review analyzes patent applications published up to 2023 on hydrogen generation via catalytic AB hydrolysis. The patent search yielded 99 patent publications, which were examined not only by country and research institution but also by two representative types of catalysts derived from noble metal (abbreviated hereafter as NM) and non-NM. Based on the analysis, future research and development was discussed.

“…Among these, amine-borane stands out as an effective hydrogen storage material because it satisfies a number of requirements set by the United States Department of Energy (DOE): (a) possessing a significant amount of hydrogen, (b) stability, and (c) eco-friendliness [ 8 , 9 ]. Ammonia borane (NH 3 BH 3 ) is the most basic form of the amine-borane compounds that is being studied for its potential use in solid hydrogen storage material due to its high (19.6 wt.%) hydrogen content [ 10 , 11 ]. Hydrogen produced by the photocatalytic hydrolysis of AB with the help of light has attracted a lot of attention because it is a promising clean, efficient, and infinite energy source [ 11 , 12 ].…”

The present study involves the synthesis of photocatalytic composite nanofibers (NFs) comprising ilmenite nickel titanite-supported carbon nanofibers (NiTiO3/TiO2@CNFs) using an electrospinning process. The photocatalytic composite NFs obtained were utilized in hydrogen (H2) production from the photohydrolysis of ammonia borane (AB). The experimental findings show that the photocatalytic composite NFs with a loading of 25 mg had a good catalytic performance for H2 generation, producing the stoichiometric H2 in 11 min using 1 mmol AB under visible light at 25 °C and 1000 rpm. The increase in catalyst load to 50, 75, and 100 mg leads to a corresponding reduction in the reaction time to 7, 5, and 4 min. The findings from the kinetics investigations suggest that the rate of the photohydrolysis reaction is directly proportional to the amount of catalyst in the reaction system, adhering to a first-order reaction rate. Furthermore, it was observed that the reaction rate remains unaffected by the concentration of AB, thereby suggesting a reaction of zero order. Increasing the reaction temperature results in a decrease in the duration of the photohydrolysis reaction. Furthermore, an estimated activation energy value of 35.19 kJ mol−1 was obtained. The composite nanofibers demonstrated remarkable and consistent effectiveness throughout five consecutive cycles. The results suggest that composite NFs possess the capacity to function as a feasible substitute for costly catalysts in the process of H2 generation from AB.
