Hydrogenation Study of NaF/NaH/MgB2 Reactive Hydride Composites

The Journal of Physical Chemistry C, 2017
The hydrogenation of NaF/9NaH + 5MgB2 and NaF/2NaH + 1.5MgB2 reactive hydride composites (RHC) was studied by volumetric titration (kinetics and PCI curves), in situ synchrotron radiation powder X-ray diffraction (SR-PXD), high-pressure differential scanning calorimetry (HP-DSC), Fourier transform infrared spectroscopy (FT-IR), and scanning electron ...

Milling time effect of Reactive Hydride Composites of NaFNaHMgB2 investigated by in situ powder diffraction

International Journal of Hydrogen Energy, 2016
Abstract Light metal complex borohydrides have high hydrogen storage capacities but suffer from drawbacks of slow hydrogen sorption kinetics, poor reversibility and high thermodynamic stability. The NaF + 9NaH + 5MgB2 composite has a theoretical hydrogen capacity of 7.7 wt% H assuming the formation of 10NaBH3.9F0.1 + 5MgH2.
