Summary: We studied the synthesis reaction of Mg2NiH4 hydride films and found that a dense polycrystalline film of Mg2NiH4 hydride grows on a thin underlayer of intermetallic alloy MgNi2. The interface between MgNi2 and Mg2NiH4 is the most probable location of the growth reaction. We also observed cathode luminescence spectra of the Mg2NiH4 hydride film, which showed that Mg2NiH4 is an indirect gap semiconductor with a gap value of approximately 1.6 eV.

Summary: The study investigated a multi-component AB(2) type hydrogen storage intermetallic alloy, where the addition of oxygen did not significantly change the PCT properties but slightly increased the plateau pressure. Both AB(2) and AB(2)O(0.05) alloys were found to be excellent candidates for H-2 storage, with the addition of oxygen improving hydrogen absorption kinetics in the AB(2) alloy.

Summary: Hydrogen storage remains a huge challenge for the development of a sustainable energy system, despite its importance. Light metal hydrides have high hydrogen densities but suffer from slow kinetics and poor reversibility due to strong bonds between metal atoms and hydrogen. Nanoscale particles offer a promising solution to tailor the properties of light metal hydrides and improve their performance. This review summarizes the preparation methods and hydrogen storage performance of nanostructured light metal hydrides, discusses the challenges, and explores future research prospects, highlighting the combination of nanostructuring and nanocatalysis for practical hydrogen carriers.

Summary: Developing safer and more efficient hydrogen storage technology is crucial for the realization of the hydrogen economy. MgH2 has been extensively studied as a promising solid-state hydrogen storage material due to its lightweight, high storage density, and abundant reserves. However, practical applications have been hindered by issues such as stable thermodynamics, sluggish kinetics, and rapid capacity decay.

Summary: The study demonstrates a new approach to thermodynamically stabilizing metastable metal hydrides by coordinating them with nitrogen binding sites within nanopores. This allows for low-temperature hydrogen release and regeneration of LiAlH4 at high pressure, with a predicted decrease in Al-H bond dissociation energy. Additionally, solid-state reversibility is achieved through a combination of nanoconfinement effects, Li adatom formation, and charge redistribution between the metal hydride and the host.

Summary: Hydrogen energy is proposed as a promising energy replacement to resolve the current energy problems for sustaining the long-term development of human society and eventually achieving the hydrogen economy. Seeking appropriate non-noble metal-based catalysts is the vital step that is needed to improve the sluggish kinetics of the hydrolysis process. The study systematically discusses different non-noble metal-based catalysts and emphasizes the importance of developing sustainable and clean hydrogen energy.

Summary: A new kinetic model for the hydrogensulfide scavenging reactions using MEA-triazine (HET) is proposed, supported by experimental observations obtained by NMR spectroscopy. The model assumes the existence of 3,5-bis-(2-hydroxyethyl)-hexahydro-1,3,5-thiadiazine (TDZ) as a reaction intermediate. Experimental data were obtained using in situ Raman spectroscopy, and the optimal model parameters were determined through regression analysis. The rate constants and activation energies for the scavenging reactions were also estimated.
