Summary: Developing safer and more efficient hydrogen storage technology is crucial for the realization of the hydrogen economy. MgH2 has been extensively studied as a promising solid-state hydrogen storage material due to its lightweight, high storage density, and abundant reserves. However, practical applications have been hindered by issues such as stable thermodynamics, sluggish kinetics, and rapid capacity decay.

Summary: The storage of hydrogen in a compact, safe and cost-effective manner is crucial for a more sustainable society. Magnesium hydride (MgH2) has attracted attention as a hydrogen carrier but its practical use is limited due to high temperatures and slow kinetics. Catalysis plays a crucial role in enhancing hydrogen cycling kinetics, and research has focused on designing and optimizing catalysts for Mg/MgH2.

Summary: In this study, a high-efficient catalyst comprising of YCxFy nanosheets-supported Ni nanoparticles was designed to address the sluggish kinetics and poor cyclic stability of MgH2. The as-achieved MgH2-10 wt.% Ni-30/YCxFy composite exhibits superior hydrogen desorption kinetics and high capacity retention. The in situ formed Mg2NiH4 and YH3 catalytic phases accelerate the hydrogen desorption kinetics, while the dispersed MgF2 and carbon species prevent the crystallite growth, particle aggregation, and catalyst redispersion, contributing to an excellent cyclic stability.

Summary: The high operation temperature limits the practical applications of magnesium hydride. The hydrogenation performance at relatively low temperatures degrades rapidly during cycling. However, the hydrogenation kinetic rate can be restored by subjecting the performance-degraded sample to an ultra-high-energy high-pressure planetary ball mill again. The nanocrystalline structure with a high concentration of defects in the ball-milled Mg-based material is critical for achieving a good kinetic rate of hydrogen adsorption at room temperature. The defect concentration effects on hydrogen absorption are more significant than crystallite size.
