英文摘要in this paper, an effective method to produce hydrogen via the hydrolysis of the milled al-bi-hydride (or salts) in pure water at room temperature has been found. the result shows that the al-bi-hydrides (or salts) prepared by 5 it milling appear very effective to improve their hydrolysis reactivity. and the milled al-bi-hydrides (or salts) have high hydrogen yield in pure water, especially the al-10 wt.% bi-10 wt.% mgh2 mixture or al-10 wt.% bi-10 wt.% mgcl2 mixture all can produce 1050 ml/g within 5 min. the improvement mainly comes from three factors: (1) the additives (mgh2, cah2, licl, mgcl2, kci, etc.) play an important role to decrease the mean size of the mixture particles; (2) the exothermic dissolution of the salt additive such as mgcl2 can increase the temperature of aqueous solution, favoring the reaction between al-bi composite and water; (3) the hydrolysis of the additives can also offer conductive ions on the work of the micro-galvanic cell of al-bi composite. furthermore, the high conductive ions around the al-bi composite are the uppermost effect for increasing the hydrogen yield and hydrogen generation rate.
