The preliminary studies on MgH2 as hydrogen storage material by inserting dual catalysts, iron
oxide and silicon carbide (5wt% Fe2O3 and SiC), has been done. The sample was prepared
using reactive ball milling technique for 10 hours. The milling process was done under 10 bar
hydrogen pressure. Phase investigation using X-ray diffraction showedthat after 10 hours of
milling, the MgH2 emerged as the dominant phase and the crystallite size decreased to
nanometer scale. The morphological observation obtained by scanning electron microscope
showed that the powder material surface is irregular, as a result of repeated during the milling
process. Finally,DTA scan showed the onset temperature at 354o
Cwhich is still high for the
automotive application.
