Popis: Though the alloy, Mg 2 Ni, has desirable properties for storageof hydrogen, its application has been hindered by the difficulty of its initial activation for hydrogenuptake. A number of methods have been reported for activation of Mg 2 Ni. While someof these methods utilize aqueous solutions, there has been no report of activation with pure water.It has been demonstrated in this laboratory that magnesium nickel alloy can be activated forhydrogen uptake by treatment with water for as little as 2 min. Increasing the treatment time withwater increases the amount of hydrogen absorbed and increases the longevity of the activation.Thermal data, scanning electron microscopic data, and x-ray photoelectron spectroscopic data arepresented in a discussion of the activation of magnesium nickel alloy with water.
