In this work, the researchers prepared metallic iron (Fe) nanoparticles on calcium hydride (CaH 2) particles, with a mixture of barium oxide (BaO) and barium hydride (BaH 2) deposited on them.

Instead, Kageyama and his colleagues introduced an ordered structure into a barium hydride crystal, which caused hydrogen anions to move significantly faster even at 200°C.

Barium heat-treated to 200°C (392°F) in a hydrogen gas it forms barium hydride (BaH 2), a grey powder that decomposes on contact with water and can be used as a source of nascent hydrogen for life ...

Hydride: A species in which hydrogen exists as a negatively charged ion (H–), often key in facilitating catalytic hydrogenation reactions. Alkaline Earth Metal Complexes and Catalysis ...

A group of scientists from Russia, China, and the United States predicted and then experimentally obtained barium superhydrides' new unusual superconductors. The study was published in Nature ...

To achieve the hydride superionic conductivity, the researchers synthesized the oxyhydride, Ba 1.75 LiH 2.7 O 0.9 (BLHO), which has a layered structure of Barium, Lithium, Hydrogen and Oxygen.

Theoretical studies revealed that surface barium hydride species play a multifaceted role, enabling deprotonation of sp 3 C-H bonds and nucleophilic attack on the sp 2 C atoms to yield ...
