摘要：

Mechanically milled 3LiBH(4)/TiF3 mixture can rapidly release over 5 wt % hydrogen at moderate temperatures (70-90 degrees C) without undesired gas impurity. Structure analyses results show that the favorable dehydrogenation performance of the material should be associated with the in situ formation and rapid decomposition of an intermediate titanium borohydride (Ti(BH4)(3)). These findings demonstrated a viable chemical activation approach for promoting hydrogen release from the thermodynamically stable borohydrides. Particularly, it shows the potential of transition metal borohydrides for hydrogen storage applications.
