“…Therefore, CoeB has excellent catalytic properties. According to Chater et al [13], Na 2 NH 2 BH 4 can be prepared by heating NaNH 2 eNaBH 4 (1/ According to this point of view, we speculate the mechanism of the decomposition of NaNH 2 eNaBH 4 (2/1) promoted by CoeB can be divided into two major stages, as illustrated in Fig. 6, which is in consistent with the TG curve in Fig.…”

“…So far, there are a few researches focusing on composite NaNH 2 eNaBH 4 systems. Chater et al [13] and Somer et al [14] synthesized composite NaNH 2 eNaBH 4 systems by annealing the raw materials in sealed quartz tube or glass ampoule, while we achieved similar NaNH 2 eNaBH 4 systems via ball milling [15]. All these studies indicate the composite NaNH 2 eNaBH 4 is promising for developing new hydrogen storage materials.…”

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.

Abstract:The development of new practical hydrogen storage materials with high volumetric and gravimetric hydrogen densities is necessary to implement fuel cell technology for both mobile and stationary applications. NaBH4, owing to its low cost and high hydrogen density (10.6 wt%), has received extensive attention as a promising hydrogen storage medium. However, its practical use is hampered by its high thermodynamic stability and slow hydrogen exchange kinetics. Recent developments have been made in promoting H2 release and tuning the thermodynamics of the thermal decomposition of solid NaBH4. These conceptual advances offer a positive outlook for using NaBH4-based materials as viable hydrogen storage carriers for mobile applications. This review summarizes contemporary progress in this field with a focus on the fundamental dehydrogenation and rehydrogenation pathways and properties and on material design strategies towards improved kinetics and thermodynamics such as catalytic doping, nano-engineering, additive destabilization and chemical modification.
