Paper Abstract

A temperature dependent Raman scattering study was conducted for the first time on LiAlH4 and Li3AlH6 in an effort to monitor the reaction kinetics of these hydrides toward its application as a hydrogen storage/delivery system for fuel cell and other applications. LiAlH4 demonstrated a gradual softening of its Raman modes as the temperature was increased from 25 to 145 °C while Li3AlH6 demonstrated a loss in its Raman signal as the temperature increased from 30 to 90 °C. The more sensitive Raman response of Li3AlH6 is believed to be the result of the weaker attraction between the octahedral AlH63- units in the anionic network of the Li3AlH6 compared to the tetrahedral AlH4- units of LiAlH4.
