Chloride-substitution in sodium borohydride

Autor: Magnus H. Sørby, Bjørn C. Hauback, Jørn Eirik Olsen

Publikováno v: Journal of Alloys and Compounds. 509:L228-L231

The changes in structure and stability of NaBH4 on Cl-substitution obtained in mechanochemical reactions between NaBH4 and NaCl have been investigated by conventional and synchrotron radiation powder X-ray diffraction, differential scanning calorimet

Reversible Hydrogenation Studies of NaBH4 Milled with Ni-Containing Additives

Autor: Bjørn C. Hauback, Isabel Llamas-Jansa, Terry D. Humphries, Georgios N. Kalantzopoulos, Jørn Eirik Olsen

Publikováno v: Journal of Physical Chemistry C

NaBH4 has long been identified as a viable hydrogen-storage material due to a theoretical gravimetric H2 capacity of 10.6 wt %. Because of the high enthalpy of decomposition of 108 ± 3 kJ mol–1, thermal decomposition of the pristine material does

Crystal structures and properties of solvent-free LiYb(BH4)4−xClx, Yb(BH4)3 and Yb(BH4)2−xClx

Autor: Bjørn C. Hauback, Christoph Frommen, Magnus H. Sørby, Jørn Eirik Olsen

Publikováno v: RSC Advances. 3:10764

Metal borohydrides offer high theoretical storage capacity for solid state hydrogen storage. This work is aimed at the mechanochemical synthesis of Yb(BH4)3 from LiBH4 and YbCl3. Different synthesis routes resulted in three new compounds, LiYb(BH4)4�
