Abstract：Magnesium-based hydrogen storage materials have been widely studied due to its high hydrogen storage capacity, low cost, and abundant raw material availability. However, magnesium-based hydrogen storage materials also suffer from shortcomings such as high hydrogen absorption and desorption temperatures, and slow absorption and desorption rates. These limitations restricted the large-scale commercial application of magnesium-based hydrogen storage materials. In recent years, numerous researchers focused on modifying magnesium-based hydrogen storage materials to improve their hydrogen absorption and desorption kinetics as well as thermodynamic properties, with significant progress already achieved. Based on the current research status of hydrogen storage materials both domestically and internationally, the hydrogen storage mechanism and material preparation methods of magnesium-based hydrogen storage materials were summarized. The modification methods for magnesium-based hydrogen storage materials were elaborated, including the effects of particle size reduction, catalyst addition, doping, and elemental addition or substitution on the hydrogen absorption and desorption performance. Furthermore, the characteristics of these modification methods were analyzed and compared. Finally, an outlook was offered on the future development and modification research directions for magnesium-based hydrogen storage materials.
