Abstract

This study is aimed at developing novel hydrides for hydrogen storage through a new synthesis technique utilizing high hydrogen overpressure at elevated temperatures denoted as Molten State Processing, MSP. This synthesis technique holds the potential of fusing different known complex hydrides at elevated temperatures and pressures to form new complexes having different sorption and thermodynamic properties. Complex hydrides produced by this method (e.g. NaMgH3, K3AlH6 and Na2LiAlH6) were identified through structural determination and thermodynamic characterization.
