RESULTS
Towards room temperature, direct, solvent free synthesis of
tetraborohydrides, e.g. LiBH4
Due to their high hydrogen content, tetraborohydrides are discussed as potential synthetic
energy carriers. On the example of lithium borohydride LiBH4, we discuss current
approaches of direct, solvent free synthesis based on gas solid reactions of the elements
or binary hydrides and/or borides with gaseous H2 or B2H6. The direct synthesis from the
elements requires high temperature and high pressure (700°C, 150bar D2). Using LiB or
AlB2 as boron source reduces the required temperature by more than 300 K.
