Recent advances of nanoconfinement in Mg related hydrogen storage materials: A minor review

Hydrogen is regarded as an ideal clean energy because of its high calorific value and easy accessibility characteristics. However, storing hydrogen in a compact, inexpensive, and safe way is a main restriction for booming the hydrogen energy. Magnesium-based hydrogen storage material is considered as a promising solid hydrogen storage material with the advantages of large hydrogen storage capacity (7.6wt%), good performance and low cost. However, it is still needed to overcome the obstacles of high thermodynamic stability and slow kinetic. In this paper, we review the recent advances of nanoconfinement in Mg related hydrogen storage materials by loading Mg particles to different supporting materials, including carbons, metal-organic frameworks and other materials. Perspectives are also provided for designing high performances of Mg materials using nanoconfinement.
