Decomposition behaviour of Mn(BH4)2 formed by ball-milling LiBH4 and MnCl2

Promoted hydrogen release from 3LiBH4/MnF2 composite by doping LiNH2: Elimination of diborane release and reduction of decomposition temperature

“…Moreover, at the LiNH 2 content of 10 wt.% and 15 wt.%, strong peaks at about 19 attributed to Mn(BH 4 ) 2 can be found in Fig. 1(e and f), confirming the cation exchange of LiBH 4 and MnF 2 after doping LiNH 2 [20]. Because MnF 2 does not directly react with LiNH 2 to produce LiF under this preparation condition (see Fig.…”

Mechano-chemical synthesis of manganese borohydride (Mn(BH4)2) and inverse cubic spinel (Li2MnCl4) in the (nLiBH4 + MnCl2) (n = 1, 2, 3, 5, 9 and 23) mixtures and their dehydrogenation behavior

“…Beside the LiCl diffraction peaks they observed some unidentified diffraction peaks which were later identified as belonging to Mn(BH 4 ) 2 as it was at the same time reported in [14e16]. Very recently, Liu et al [17] reported limited studies of thermal decomposition behavior of LiBH 4 ball milled with MnCl 2 with the molar ratio n ¼ 2 and 3. From Differential Scanning Calorimetry (DSC) and TG (thermogravimetric) analysis they deduced that dehydrogenation of Mn(BH 4 ) 2 occurs with the release of diborane (B 2 H 6 ).…”

“…The obtained results mean that the quantity of released diborane is miniscule being barely on the verge of the resolution of the Hiden Sieverts apparatus-quadrupole mass spectrometric experimental system. It must be pointed out that Liu et al [17] reported that the relatively low intensity of diborane peaks they observed in their thermogravimetric experimental set up was due to the fact that large quantities of diborane did not reach the mass spectrometer. They observed some borate deposits on the piping system.…”

Tailoring the Properties of Ammine Metal Borohydrides for Solid‐State Hydrogen Storage

“…The MS signals (Figure 12) show that a mixture of diborane and hydrogen is released in accordance with the literature. [52,53] In addition, two weak endothermic events are observed by DSC at 106 and 272 8C corresponding to the phase transition and the melting of traces of LiBH 4 in the sample.…”
