· JVASP-119138· Tb2Ti2Fe22H

Tb2Ti2Fe22H is an intermetallic hydride compound belonging to the rare-earth transition metal family, combining terbium, titanium, iron, and hydrogen in a structured lattice. This material is primarily of research interest for hydrogen storage and energy applications, where the metal-hydrogen interaction provides potential for reversible hydrogen absorption and desorption. Its notable characteristic is the combination of rare-earth and ferromagnetic elements, making it relevant for studies on magnetohydrogen coupling and advanced energy conversion systems where conventional alloys fall short.
