摘要：

The hydrogen desorption properties of lithium borohydride, LiBH4, ball milled with titania, TiO2, in varying proportions have been investigated. The multicomponent LiBH4-TiO2 materials have been found to dehydrogenate at much lower temperatures. For example, the onset of dehydrogenation was 150 degrees C for a LiBH4-TiO2 mixture with a mass ratio of 1:4 and the majority of the hydrogen could be released below 220 degrees C. XRD and in situ neutron diffraction results revealed that the destabilization of LiBH4 by the oxide resulted from the formation of lithium titanate.
