Study of milling time impact on hydrogen desorption from LiAlH4-Fe2O3 composites [PDF]
Processing and Application of Ceramics, 2022 LiAlH4 was modified by mechanical milling and with the addition of 5 wt.% Fe2O3 in order to improve its hydrogen desorption properties. The composite was milled for 1, 3, 5, 7 or 15min, and depending on the milling time, various phenomena took place.

Hydride Reduction by a Sodium Hydride–Iodide Composite [PDF]
Angewandte Chemie, 2016 AbstractSodium hydride (NaH) is widely used as a Brønsted base in chemical synthesis and reacts with various Brønsted acids, whereas it rarely behaves as a reducing reagent through delivery of the hydride to polar π electrophiles. This study presents a series of reduction reactions of nitriles, amides, and imines as enabled by NaH in the presence of ...

Acoustic Plasmons in Nickel and Its Modification upon Hydrogen Uptake
Nanomaterials, 2022 In this work, we study, in the framework of the ab initio linear-response time-dependent density functional theory, the low-energy collective electronic excitations with characteristic sound-like dispersion, called acoustic plasmons, in bulk ...

Noble-metal-free nanocatalysts for hydrogen generation from boron- and nitrogen-based hydrides
Inorganic Chemistry Frontiers, 2020 We focus on the recent advances in non-noble metal catalyst design, synthesis and applications in dehydrogenation of chemical hydrides (e.g. NaBH4, NH3BH3, NH3, N2H4, N2H4BH3) due to their high hydrogen contents and CO-free H2 production.
