? 2022 Elsevier B.V.Metal hydrides were discovered in the fifties and since then have been widely studied and developed, mainly for energy applications (batteries, hydrogen storage, compression.). In addition to these uses, other properties are considered such as sensors, actuators, or scavengers. This paper proposes a review of intermetallic-based materials for hydrogen gettering. The different chemistries (Zr- or Ti-based compounds) are described in terms of alloying elements and gettering properties. Various aspects, including the activation process, surface coating and resistance to impurities, are also discussed. Finally, new processes and other possible applications are discussed for these materials.
