What is Recent Advances in Designing Metal Oxide-based Catalysts to Enhance the Sorption Kinetics of Magnesium Hydride about?

Magnesium hydride (MgH 2 ) has been under spot light recently when it comes to solid-state hydrogen storage media owing to its superior hydrogen storage capacity, reasonably good reversibility, and cost-effectiveness. Albeit these advantageous attributes, it suffers from the setback of having undesirably high thermodynamic stability and exceedingly sluggish kinetics, which diminishes its feasibility for practical use. The purview of this review article is to first introduce the basic understandings related to sorption kinetic of hydrogen storage material with a emphasis on MgH 2 and to elucidate the key developments in the field of exploiting various kinds of Metal Oxide-based catalysts in improving the hydrogenation kinetics of MgH 2 . The article initiates with brief but sufficiently explanatory discussions on the rudiments of hydrogen sorption in MgH 2 followed by an elaborate exposition on the usage of catalyst as a possible means to alleviate some of the shortcomings of the virgin compound. This article assesses a number of factors affecting the catalytic efficiency, e.g., defect density, valance state of the metal ion, oxygen vacancy, etc., which dictates the metal oxide-base
