In situ X-ray Raman spectroscopy study of the hydrogen sorption properties of lithium borohydride nanocomposites

What is it about?

This is a follow-up work on our previous work on x-ray Raman spectroscopy (XRS) on LiBH4. In the present study the nanoconfined hydrogen storage material LiBH4 is measured during different stages of de- and re-hydrogenation.

Why is it important?

We show in this work that it is possible to identify the species present in nanoconfined LiBH4 during de-hydrogenation and partial re-hydrogenation. One interesting result is that we obtained that there is already partially rehydrogenation to even LiBH4 applying just 1 bar of hydrogen in the case of nanoconfined LiBH4.
