“…It will be shown later that this significant influences the chemical and mechanical properties. Similar investigations have been carried out in [22] on magnesium nitride films deposited by pulsed laser deposition. They determined the exact same binding energies.…”

“…As seen in Figure 7, the deconvoluted spectrum of the postheated sample at 100 °C clearly shows two peaks from chemically different Mg entities. The bonding state at 49.3 eV corresponds to elemental Mg, but the other one at higher energy side (52.1 eV) cannot be assigned to any known Mg-containing chemicals, including Mg nitride (Mg 3 N 2 , 50.5 eV) 39 and Mg boride (MgB 2 , 49.5 eV). 40 The unknown chemical state of Mg was observed to gain intensity and slightly shifted to low-energy side with increasing dehydrogenation temperature, and ultimately it became the predominant chemical state of Mg in the sample after being held at 300 °C for 2.5 h (point D in Figure 3).…”

Mechanically Milling with Off-the-Shelf Magnesium Powder to Promote Hydrogen Release from Ammonia Borane

Mechanically milling with the off-the-shelf magnesium (Mg) powder can dramatically improve the dehydrogenation properties of ammonia borane (AB) on all key aspects: enhancing the dehydrogenation kinetics, reducing the induction period, suppressing the formation of volatile byproduct, and alleviating the sample foaming. The postmilled AB/0.5Mg sample can release 8.2 wt % of hydrogen at 100 °C within 4 h and deliver >2.5 equiv of hydrogen in AB upon elevating the dehydrogenation temperature to 300 °C, giving a material-based hydrogen capacity of 12 wt %. Additionally, the dehydrogenation reaction of the AB/0.5Mg sample becomes significantly less exothermic than that of pristine AB, and remarkably, the third dehydrogenation step is tailored to be endothermic. Combination of phase/structure/chemical state analyses suggest that a considerable amount of Mg participates in the dehydrogenation process, resulting in the formation of Mg-N-B-H product(s).

“…This process allows the preparation of mesoporous structures with a high specific surface area, well adaptable to catalytic application [4]. A number of processing techniques have been developed for the deposition of coatings, such as spray pyrolysis [5], chemical vapor deposition [6], physical vapor deposition [7], sputtering [8] and dip-coating [9]. In the sol-gel process, organic polymers are often applied to improve the strength of the produced alumina coatings [10], although they can affect the relative density [11].…”
