Hydrogen production using AlGaInSn alloy with semi-solid structures

Semi-solid AlGaInSn bulk was fabricated for hydrogen production by Al-water reaction, of which the semi-solid structure was characterized by near-sphere primary phases dispersed within active metals enriched fine secondary-solidification-structures. The unique structure gives rise to a dramatic hydrogen production compared with the cast counterpart, although uneven throughout the whole bulk and hard to control. The underlying mechanism is...
