Hydrogen is regarded as a promising solution to fulfill the energy demand of Mars human base in future. Through in-situ resource utilization (ISRU) on Mars, composite metal-organic frameworks (MOFs) and magnesium hydride which demonstrates synergistic effect physi- chemisorption has been proposed be an attractive approach for long-term hydrogen storage. MOFs may act either scaffolds confine Mg ...

Light-metal hydrides, like MgH2, remain under scrutiny as prototypes for reversible H-storage materials. For MgH2, we assess hydrogen desorption/adsorption properties (enthalpy and kinetic barriers) for stepped, catalyst-doped surfaces occurring, e.g., from ball-milling in real samples. Employing density functional theory and simulated annealing in a slab model, we studied initial H2 desorption...

Mg (MgH2)-based composites, using carbon nanotubes (CNTs) and pre-synthesized vanadium-based complex (VCat) as the catalysts, were prepared by high-energy ball milling technique. The synergistic effect of coupling CNTs and VCat in MgH2 was observed for an ultra-fast absorption rate of 6.50 wt. % of hydrogen per minute and 6.50 wt. % of hydrogen release in 10 min at 200 °C and 300 °C, respective...

The Cover Feature shows a concerted carbonyl hydroboration mechanism involving Mg−O, B−H, and C=O bonds. Homoleptic magnesium alkoxides catalyze ketone with turn-over frequency (TOF) reaching up to 59,400 h−1 exhibit exceptional functional group tolerance. This TOF is so far the best observed in main catalyst without involvement of metal hydride intermediate. newly proposed finds general applic...

MgH2 is one of the most promising hydrogen storage materials due to its high capacity and favorable reversibility, but it suffers from stable thermodynamics poor dynamics. In present work, an intersected Y2O3/NiO hybrid with spherical hollow structure synthesized. When introduced via ball-milling, spheres are crushed into ultrafine particles, which homogenously dispersed in MgH2, showing a high...
