Abstract:
1. A method of synthesizing magnesium-cobalt pentahydride, comprising: melting a magnesium (Mg) metal and a cobalt (Co) metal at a first temperature, wherein the content of the cobalt metal is substantially 30 atom percent (at %), and the first temperature is between the melting point of the magnesium metal and the melting point of the cobalt metal, thereby forming a molten metal; cooling the molten metal to a second temperature and then isothermally heating the molten metal for forming a MgCo cooling down the MgCo performing a ball-milling step onto the MgCo performing a hydrogenation step onto the metal mixture powder for up to 15 hours at a temperature of substantially 100° C. to 600° C. under a hydrogen pressure of substantially 6 atm (atmosphere) to 120 atm so as to form magnesium-cobalt pentahydride (Mg
