Abstract

Hydrogen release from Al-based complex hydrides composed of metal cation(s) and [AlH4]− was investigated using inelastic neutron scattering viewed from vibrational dynamics. The hydrogen release followed the softening of translational and [AlH4]− librational modes, which was enhanced by vibrational dynamics and the valence(s) of the metal cation(s).
