Ammonia borane (NH3BH3, AB) is an intriguing molecular crystal with extremely high hydrogen capacity and moderate thermal stability. In the present study, we show a simple but effective approach for destabilizing AB promoted release at temperatures. It found that mechanically milling magnesium hydride (MgH2) can dramatically improve dehydrogenation properties of AB, on both kinetic thermochemical aspects. For milled AB/0.5MgH2 material, over 8 wt% be released from within 4 h around 100 °C...
The synthesis of magnesium amidoborane, Mg(NH2BH3)2 (MgAB), has been attracting considerable interest since the recognition potential metal amidoboranes as promising hydrogen storage media. But so far, all efforts for synthesizing using mechanochemical or wet chemistry methods have frustrated. In this paper, we report a successful MgAB ammonia borane (AB) and hydride (MgH2) (Mg) powder starting materials. It was found that post-milled 2AB/MgH2 2AB/Mg mixtures undergo solid-phase reactions...
As a consequence of the combination formation and decomposition reactions NaMg(NH(2)BH(3))(3), 3NH(3)BH(3)/NaMgH(3) mixture can rapidly release ca. 10 wt.% hydrogen at 80 °C within 2 min.
Nickel phosphides have been widely explored for electrocatalytic hydrogen evolution reaction (HER) due to their high activity and durability. To date, however, it is still a big challenge develop facile scalable approaches preparing nickel phosphide structures with HER performance practical applications. Here, general strategy demonstrated preparation of porous nanosheets on arbitrary substrates by electroless Ni plating the substrate followed convenient stable phosphidation reaction....
Lithium borohydride, LiBH4, possesses high hydrogen capacity, but cannot be used for storage owing to the problematic H-exchange kinetics and thermodynamics. In present study, we employed Li+−Ca2+ combination strategy improve de/rehydrogenation properties of LiBH4. Our study found that mechanically milling 1:1 LiBH4/Ca(BH4)2 mixture formed a dual-cation Li0.9Ca(BH4)2.9, which then transformed stoichiometric LiCa(BH4)3 in heating process. The formation decomposition behaviors were studied...
Hydrogen release from ammonia borane (NH3BH3, AB) can be greatly promoted by mechanical milling with magnesium nitride (Mg3N2). For example, a post-milled 6AB/Mg3N2 sample started to hydrogen ∼65 °C and gave material-based capacity of ∼11 wt% upon heating 300 °C. In addition the improved dehydrogenation kinetics, also showed satisfactory performance in suppressing volatile byproducts. X-ray diffraction, Fourier transform infrared spectroscopy solid-state 11B MAS NMR, as well series designed...
Mechanically milling with the off-the-shelf magnesium (Mg) powder can dramatically improve dehydrogenation properties of ammonia borane (AB) on all key aspects: enhancing kinetics, reducing induction period, suppressing formation volatile byproduct, and alleviating sample foaming.

A high-efficient and low-cost catalyst on hydrogen isotope separation between water is an essential factor in industrial application for heavy production detritiation. In past studies, Pt-based catalysts were developed but not practical commercial use due to their high cost vapor phase catalytic exchange (VPCE), while impregnated nickel with a lower the problems of agglomeration low Ni utilization existed. Therefore, solve these problems, in-situ grown Ni-based (NiAl-LDO) derived from...
It is ideal that the hydrogen storage materials for vehicular applications can desorb substantial amounts of below 85 °C, operating temperature polymer electrolyte membrane (PEM) fuel cells. Ammonia borane (NH3BH3, AB short), because its intriguingly high density (i.e., 19.6 wt %) and moderate thermal stability, widely regarded as a promising on-board medium. However, at this temperature, both dehydrogenation kinetics deliverable H-capacity are far from meeting requirements practical...
