Lithium MagnesiumAmide chlorides Powder X-ray diffraction a b s t r a c t Two new amide chloride phases, with approximate stoichiometries Li 7 (NH 2 ) 6 Cl and Li 6 Mg 0.5 (NH 2 ) 6 Cl, have been identified by powder X-ray diffraction, and their hydrogen storage properties studied. Both phases released hydrogen on reaction with LiH at a lower temperature than observed for lithium amide, and ammonia release was suppressed. The chloride ions were maintained within the structure after hydrogen desorption and rehydrogenation, raising the possibility that the materials might be cycled. The desorption properties of Li 7 (NH 2 ) 6 Cl were found to be similar to the previously reported amide chloride Li 4 (NH 2 ) 3 Cl but with a much reduced gravimetric penalty owing to chloride incorporation.Rehydrogenation of the imide products of reaction of both Li 7 (NH 2 ) 6 Cl and Li 6 Mg 0.5 (NH 2 ) 6 Cl with LiH occurred more readily at 90 bar and 300 C than that of Li 4 (NH 2 ) 3 Cl.

“…According to the results of Li et al [18] and Hu et al [23], this absorbance is assigned to the MgNH. Liu et al [17] also reported that MgNH was easily obtained by ball milling LiNH 2 eMgH 2 at molar ratio of 1:1. Thus, MgNH appeared in the Li 3 NeLiNH 2 eMgH 2 sample during the ball milling and disappeared in the Li 3 NeLiNH 2 e2MgH 2 .…”

The development of hydrogen storage materials with favorable thermodynamics (e.g., kinetics, desorption/adsorption temperature) has attracted considerable attention in recent years. Alanates, amide-hydride mixtures and magnesium hydride are the candidates with the most potential storage material due to their high hydrogen storage capacity and good reversibility, but each has its own limitations (e.g., high desorption temperature and sluggish kinetics). Carbon has many allotropes such as graphite, activated carbon, fullerenes, carbon nanotubes, and the most recent, graphene, etc. These have novel properties which are useful in many new innovative applications. Several recent investigations have also demonstrated the benefi cial effect of carbon materials as catalyst for enhancing sorption behavior of different light hydrogen storage materials. Carbon with a small curvature radius exhibits prominent "catalytic" effect for light metal and complex hydrides. The reduction in curvature radius of carbon nanostructures enhances the electron affi nity and interaction of carbon with hydrogen because the hydrogen release/combination energy has been changed, and consequently, the de-/rehydrogenation kinetics of the material is improved. In this chapter, we will highlight the current advances (including our recent works) in the hydrogen sorption enhancement of metal and complex hydrides by incorporating carbon nanomaterials as a catalyst. There will be a particular emphasis on carbon nanotubes,
