A novel aluminum alloy which could react with water and generate hydrogen at room temperature was prepared via mechanical alloying(MA).The results shows that milling time,additives and mass ratio have a significant role in the hydrogen production rate.The highest hydrogen production rate of alloys reaches 95% of theoretical value.The velocity of hydrogen generation reaches more over 200 mL/min for a gram alloy.Active materials(Ga and In) included in the aluminum alloys can be recycled and used repeatedly.The hydrolysis reaction between aluminum and H2O will take place and release a large amount of heat,which contributes to increasing the velocity of hydrogen generation.The reaction products consist of AlO(OH) and hydrogen.
