Abstract


The influence of in-situ formed Al from hydrogenation of Al12Mg17 on hydrogen desorption properties of MgH2 was studied in this paper. Pure Al powders were also added to MgH2 by mechanical milling method and corresponding desorption properties was studied for comparison. Both of the samples showed enhanced hydrogen desorption properties than pure MgH2 while in-situ formed Al exhibited better catalyst effects than metallic Al powders.
