DOI: 10.1002/adem.201900027

Abstract: Magnesium hydride (MgH2) and titanium hydride (TiH2) are two potential candidates for solid‐state hydrogen storage, but strong hydride formation energy in these hydrides undesirably results in their high dehydrogenation temperature. First‐principles calculations show that the… read more here.
