STRUCTURAL AND HYDRIDING PROPERTIES OF COMPOSITE Mg-ZrFe_(1.4)Cr_(0.6)

摘要

The composite system Mg- ZrFe_(1.4)Cr_(0.6) was synthesized by mechanical grinding of Mg mixed with various amounts of ZrFe_(1.4)Cr_(0.6). The hydrogenation performance of Mg in the composite system was markedly enhanced, especially for Mg-40 wt. percent ZrFe_(1.4)Cr_(0.6). SEM, TEM, EDS and X-ray diffraction were used to characterize the composite. The full exploitation of the catalytic function of ZrFe_(1.4)Cr_(0.6) and the nanostructure of Mg were found to be the main reasons for the markedly improved hydriding kinetics of the composite.
