Liquid phase-enabled reaction of Al–Ga and Al–Ga–In–Sn alloys with water

The water-reactivity of Al–Ga and Al–Ga–In–Sn alloys is investigated as a means to utilize the chemical potential energy of Al to split water for the production of H2. Al in bulk quantities of these alloys participates in a heterogeneous reaction with water to produce H2 and α-Al(OH)3 (bayerite). Low melting point phases in these alloys are believed to enable the observed reaction upon liquefaction by providing a means of transport for Al in the...
