Hydrogen release reactions of Al-based complex hydrides enhanced by vibrational dynamics and valences of metal cations

Hydrogen release from Al-based complex hydrides composed of metal cation(s) and [AlH 4 ] − was investigated using inelastic neutron scattering viewed from vibrational dynamics. The hydrogen release followed the softening of translational and [AlH 4 ] − librational modes, which was enhanced by vibrat...

Zusammenfassung:Hydrogen release from Al-based complex hydrides composed of metal cation(s) and [AlH 4 ] − was investigated using inelastic neutron scattering viewed from vibrational dynamics. The hydrogen release followed the softening of translational and [AlH 4 ] − librational modes, which was enhanced by vibrational dynamics and the valence(s) of the metal cation(s). Inelastic neutron scattering spectra of LiCa(AlH 4 ) 3 upon heating and the local atomic structure around [AlH 4 ] − .
