“…If the cost of borohydride production can be reduced to US$ 0.55 kg −1 , the DBFC will be a powerful competitor in the vehicle applications of fuel cell. Recently, there are several publications related to the new processes of borohydride synthesis [14,[19][20][21]. We expect that a breakthrough can be achieved in reducing borohydride production cost.…”

“…(a) Mechano-chemical process [25,26] In 1999, a mechano-chemical method that applies the high-speed ball-milling technique was successfully introduced to synthesize SBH by using MgH 2 as the protide donor and the oxygen acceptor in the reaction shown as Eq. (11).…”

Alkali borohydrides MBH 4 and their deuterides have been investigated by X-ray and neutron powder diffraction (M = K, Rb, Cs) and by infrared and Raman spectroscopy (M = Na, K, Rb, Cs). At room temperature the compounds crystallize with a cubic high temperature (HT) structure having Fm3m symmetry in which the [BH 4 ] − complexes are disordered. At low temperature (LT) the potassium compound transforms into a tetragonal low temperature structure having P4 2 /n mc symmetry in which the [BH 4 ] − complexes are ordered such as in the isotypic sodium congener. The B-H distances within the complex as measured on the deuteride at 1.5 K are 1.205(3) Å. Indications for a partial ordering in the rubidium and cesium compounds exist but are not sufficient for a full structural characterization. Infrared and Raman spectra at room temperature are fully assigned for both hydrides and deuterides, including the overtones and combination bands, the Fermi resonance type interactions and the 10 B to 11 B splitting due to the presence of natural boron in the samples.
