Research progress in hydrogen production by hydrolysis of magnesium-based materials

Hydrogen has the characteristics of high combustion value, no pollution of combustion products, and high element content, which is considered to be the most advantageous green energy in the future. The mobile hydrogen source can achieve the preparation of hydrogen at any time, effectively avoiding the safety hazards of hydrogen in the storage and transportation process. Magnesium-based active materials, which can release hydrogen by hydrolysis at room temperature, can be ideal materials for mobile hydrogen sources. This article presents a comprehensive review of recent research progress on magnesium-based active materials, focusing on four aspects of magnesium hydrolysis reaction research: preparation methods of magnesium materials, addition of catalysts, reaction media, and applications of active magnesium-based materials. In addition, the promotion mechanism of magnesium hydrolysis reaction for different preparation methods, catalysts, and reaction media is also summarized in detail. Finally, the limitations of the current research on magnesium-based active materials are analyzed, and the future research and application aspects of this material are prospected.
