Abstract

In this study, the superior effect of RbF on reducing the hydrogen desorption operating temperature of the LiNH system was demonstrated. By doping 5 mol% RbF in the LiNH2LiH system, we obtain the lowest hydrogen desorption peak temperature (211 °C) at a heating rate of 5 °C/min, which is approximately 69 °C lower than that of the pristine LiNH2LiH system. Moreover, the system starts to desorb H2 at 120 °C, which is the lowest hydrogen desorption onset temperature. The hydrogen desorption peak and onset temperatures can be further decreased by doping more RbF. It is proposed that the RbH produced during heat treatment improves the dehydrogenation properties of the RbF-doped LiNH2LiH sample.
