Metal-Organic Frameworks Promoted Hydrogen Storage Properties of Magnesium Hydride for In-Situ Resource Utilization (ISRU) on Mars

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 nanoparticles or catalysts/precursors lower barrier dissociation surfaces. The corresponding mechanisms faster hydrogenation/dehydrogenation kinetics operation temperature were further discussed analyzed.
