Abstract

The MgH2 + 10 wt% Na3FeF6 composite resulted in both a reduced dehydrogenation temperature and enhanced sorption kinetics compared to the undoped MgH2 sample. The activation energy for the decomposition of the as-milled MgH2 was 167.0 kJ mol−1 and this value decreased to 75.0 kJ mol−1 after the addition of 10 wt% Na3FeF6 (a reduction by about 92.0 kJ mol−1).
