Abstract:

Hydrogen energy is considered to be an ideal fuel that can replace fossil fuels and achieve carbon emission reduction goals. The development, utilization and modification of high-performance hydrogen storage materials are the key to the development of hydrogen energy economy. Magnesium hydride (MgH2) has the characteristics of high mass hydrogen storage density, low cost, and environmental friendliness, and has attracted much attention in the field of solid hydrogen storage materials. However, the slow hydrogen absorption/desorption kinetics and high thermodynamic stability of MgH2 limit its practical application to a certain extent. In recent years, a lot of research work has focused on the thermal/kinetic modification of magnesium-based hydrogen storage materials, and a lot of results have been achieved so far. This paper reviews the latest research progress on improving the hydrogen storage properties of Mg-based solid hydrogen storage materials by reviewing relevant literature at home and abroad, and focuses on the research status of nanoscale research methods on nanostructures of different dimensions in Mg/MgH2 systems, aiming to provide insights and guidance for the development of advanced Mg-based hydrogen storage materials with excellent performance.

Key words: Mg-based hydrogen storage materials, Nanomaterials, Hydrogen storage performance
