DESCRIPTION:Dr. Michael FEDERHOFF\nMPI Mülheim an der Ruhr - Germany\nAlu
 minum hydride (AlH3) by itself has already been considered as a hydrogen s
 torage material over 50 years ago based on its high volumetric (148 g H2 
 L-1) and gravimetric (10.1 wt.-%) hydrogen density. Based on its low deco
 mposition temperature and light weight\, research on AlH3 confining the im
 practical re-hydrogenation conditions is still in progress. Attempts to st
 abilize AlH3 with a Lewis base\, such as an amine\, lead to a significant 
 reduction of the thermodynamic hydrogenation barrier of Al. This approach 
 enables the hydrogenation at room temperature and reasonable pressures to 
 generate amine AlH3 adducts\, called amino alanes. The influence of tertia
 ry amines leads to stabilized phases under mild conditions offering promis
 ing properties for reversible hydrogenation.\n \nReferences:\n[1]   J. O
