To investigate the energy release behaviour of reactive materials incorporating zirconium hydride (ZrH2), a comparative analysis was conducted on the energy release characteristics of polytetrafluoroethylene/aluminium (PTFE/Al), PTFE/ZrH2, and PTFE/Al ...

Hydrogen Storage Properties of Nanoconfined LiBH4–Mg2NiH4 Reactive Hydride Composites
The Journal of Physical Chemistry C, 2015LiBH4–Mg2NiH4 reactive hydride composites have been nanoconfined into two types of mesoporous carbons: a templated carbon with ordered small pores of ∼4 nm and a carbon aerogel with pores size of ∼30 nm. In situ synchrotron X-ray diffraction has revealed the formation of the MgNi2.5B2 compound during dehydrogenation at 300 °C and 5 bar of H2 pressure ...

Hydrogen back pressure remarkably promotes the formation of metal boride during the dehydrogenation of 4LiBH4 + YH3, 6LiBH4 + CeH2 and 6LiBH4 + CaH2 composites, which seems to be a general phenomenon in LiBH4-based reactive hydride composites that enables mutual destabilization between LiBH4 and metal hydride.

Acta Materialia, 1997
The intermetallic compound Mg2Ni was mechanically ground under a hydrogen atmosphere to synthesize a nanostructured composite material that is composed of nanocrystalline intra-grain and disordered inter-grain regions. Both the thermal and magnetic analyses confirmed that a volume fraction of the latter region increases twenty times as much as that in ...

For hydrogenated amorphous silicon (a-Si:H) film growth governed by SiH3 plasma radicals, the surface reaction probability b of SiH3 and the silicon hydride (–SiHx) composition of the a-Si:H surface have been investigated by timeresolved cavity ringdown and attenuated total reflection infrared spectroscopy, respectively. The surface hydride composition

ABSTRACTLiBH4 and MgH2 both have high gravimetric and volumetric hydrogen storage densities. Unfortunately, their commercial application is prevented by high thermal stability and unfavorable thermodynamic properties. Combining the two hydrides leads to a new decomposition pathway with suitable enthalpy of reaction.

The hydrogen storage properties of the Li-Mg-N-H system composed of Mg(NH2)2 and LiH are investigated. In the last decade, the Li-Mg-N-H system attracted increasing attention due to its high hydrogen storage capacity (5.5 wt.%), favourable dehydrogenation enthalpy (∆H ≈ 40 kJ∙mol-1H2) and good reversibility.
