Hydrogen Uptake of Mg/Graphite Nanocomposites Obtained by Ball Milling

摘要

Hydrogen uptake of Mg/G nanocomposites prepared by high energy ball milling of graphite (G) and Mg with organic additives (tetrahydrofuran, benzene, cyclohexane, etc.) was reviewed, combined with characterization by XRD, TPD, DSC, TGA, SEM and Raman spectroscopy. The use of organic additives during the milling process was an important factor in determining the properties of the resulting nanocomposites. Besides hydriding of the Mg component, different types of hydrogen uptake were observed for the Mg/G nanocomposites as a result of such ball milling.
