The research on the functional properties of medium- and high-entropy alloys (MEAs HEAs) has been in spotlight recently. Many significant discoveries have made lately hydrogen-based economy-related where these may be utilized all its key sectors: water electrolysis, hydrogen storage, fuel cell applications. Despite rapid development MEAs HEAs with ability to reversibly absorb hydrogen, is limited transition-metal-based that crystallize body-centered cubic solid solution or Laves phase structures. To date, no study devoted hydrogenation rare-earth-element (REE)-based HEAs, as well crystallizing face-centered-cubic (FCC) hexagonal-close-packed Here, we elucidate formation storage REE-based ScYNdGd MEA. More specifically, present astounding stabilization single-phase FCC structure induced by absorption process. Moreover, measured unprecedented high capacity 2.5 H/M observed after conducted under mild conditions proceeded without any transformation material. studied MEA can facilely activated, even a long passivation time. results complementary measurements showed desorption process proceeds two steps. In first, released from octahedral interstitial sites at relatively low temperatures. second, high-temperature process, it associated atoms stored tetrahedral sites. presented impact future novel group adaptable broad scope possible

Body-centered cubic (BCC) alloy systems can theoretically store double amounts of hydrogen compared with commercial metal hydrides at room temperature, and BCC high entropy alloys (HEAs) have shown the potential to reach this theoretic limit. However, thermodynamic stability dihydrides formed during storage results in operating temperatures. Here, by employing multi-objective Bayesian optimization-aided density functional theory calculations, we discovered 8 new HEA candidates for storage, including VNbCrMoMn that 2.83 wt% temperature atmospheric pressure, vastly exceeding capacities 1.38 1.91 LaNi5H6 TiFeH2. Such a performance is ascribed optimized absorption thermodynamics, which achieved under guidance interpretable machine learning revealed thermodynamics first second stages are largely determined bulk modulus number states d-band, respectively.
