| dc.description.abstract | MgH2 is the widely investigated and one of the most prominent solid state hydrogen storage materials because of its high hydrogen storage capacity, low cost, and enormous elemental reserves in the earth crust and seawater. However, the high desorption temperature, sluggish kinetics and high thermal stability hinder its further onboard application. In present investigation, we have reported the enhanced kinetics and thermodynamics for MgH2 catalyzed through different prominent catalysts/additives like graphene (Gr), VS2, TiH2@Gr, Ti@Gr, TiO2@Gr, and high entropy alloy (HEA). Amongst these catalysts TiH2@Gr is most suitable catalyst for empowering the kinetics and thermodynamics of MgH2. The temperature programmed study reflects that MgH2-TiH2@Gr has lowest onset desorption temperature i.e., ~231 oC with a storage capacity ~6.55 wt% which is ~190 oC lower than the desorption temperature of pristine MgH2. The better catalytic behavior of MgH2-HEA on TiH2@Gr also persists during de/rehydrogenation kinetics of MgH2. Thus, MgH2 catalyzed by HEA absorbs ~5.9 wt% of hydrogen at 300 oC under 15 atm pressures in 1.5 min. A remarkable result coming out of the present investigation is concerning cyclability (reversibility) of MgH2-HEA, up to 25 cycles. � 2022 Proceedings of WHEC 2022 - 23rd World Hydrogen Energy Conference: Bridging Continents by H2.
