Several double-cation Light metal amides for hydrogen storage and ammonia decomposition. Abstract: Hydrogen has long been touted as an alternative fuel which could form the basis of a sustainable energy system: the hydrogen economy. This thesis advances the application of light metal amide materials in the realisation of this transformative potential. The alkali metal amidozincates Li 4 [Zn(NH 2) 4](NH 2) 2 and K 2 [Zn(NH 2) 4] were, to the best of our knowledge, studied for the first time as hydrogen storage media.Compared with the LiNH 2 –2 LiH system, both Li 4 [Zn(NH 2) 4](NH 2) 2 –12 LiH and K 2 [Zn(NH 2) 4]–8 LiH systems showed improved rehydrogenation performance, especially K 2 [Zn(NH 2) 4]–8 LiH, which can be fully This work shows that ternary amides containing transition metals have great potential as hydrogen storage materials.

The mixture of K₂[Mn(NH₂)₄] and LiH showed excellent rehydrogenation properties.

READ PAPER. Made available by U.S. Department of Energy Office of Scientific and Technical Information 2020-08-13 Metal hydride materials have attracted much interest for their potential use as hydrogen storage materials.

Hydrogen desorbed from these compounds contaminated by a small amount of NH3 originated from decomposition of the amides themselves, which would be a Sodium borohydride has been considered as a solid state hydrogen storage candidate. Although practical temperatures and pressures for hydrogen storage have not been achieved, in 2012 a core–shell nanostructure of sodium borohydride was used successfully to store, release and reabsorb hydrogen under moderate conditions. Here, we review the interaction between light metal borohydrides and amides for storing hydrogen, with a special emphasis on the synthetic strategies and structural, physical, and chemical properties, which reveal a correlation between the composition, structure, and dehydrogenation properties and also provide general principles to the design of new combined systems with tailored functionality.

Several double-cation Minimal ammonia was detected and therefore the mixed cation amides could be considered as hydrogen storage materials. The reactions were found to be similar to previously studied light metal amide-hydride systems like lithium amide/lithium hydride and lithium amide/magnesium hydride. For favorable thermodynamics and the considerable kinetics of the hydrogen reaction, Li−Mg−N−H compounds hold promise as novel hydrogen storage materials for on-board usage in metal amide hydrogen storage systems. To improve their performance, much effort has been devoted to the fundamental properties of metal amides, such as electronic structure, and the energetics of their hydrogen Studies on hydrogen storage over amide–hydride systems were initiated when researchers accidentally noticed that a mixture of metallic lithium and carbon nanotubes pretreated in a purified N2 atmosphere absorbed large amounts of hydrogen at elevated temperatures (see Figure 21). The indirect hydrogen storage capabilities of Mg (NH 3) 6 Cl 2, Ca (NH 3) 8 Cl 2, Mn (NH 3) 6 Cl 2, and Ni (NH 3) 6 Cl 2 are investigated.

The synthesis and decomposition properties of some metal amides M(NH 2) x such as LiNH 2, NaNH 2, Mg(NH 2) 2 and Ca(NH 2) 2 were investigated, which play important roles for designing a new family of metal-N-H hydrogen storage systems. Both the gas chromatographic examination and X-ray diffraction measurement indicated that the reaction between alkali or alkaline earth metal hydride Shujun Qiu, Hailiang Chu, Yongjin Zou, Cuili Xiang, Fen Xu, Lixian Sun. Light metal borohydrides/amides combined hydrogen storage systems: composition, structure and properties. Journal of Materials Chemistry A 2017 , 5 (48) , 25112-25130. In addition to conventional metal hydrides, proposed hydrides for use in a hydrogen economy include complex metal hydrides, which contain a group I or II metal along with either aluminium (alanates) or boron (borohydrides), as well as some metal amides and imides, including LiNH 2, NaNH 2, Mg(NH 2) 2, LiMgN and Ca(NH 2) 2, have also been investigated for use in metal-based hydrogen storage The hydrogen desorption was also at a lower temperature than LiNH\(_2\) + LiH and 2LiNH\(_2\) + MgH\(_2\). Although hydrogen was desorbed when the mixed cation amides were heated with NaH, the amount was much smaller than for LiH and MgH\(_2\), therefore making it less suitable as a hydrogen storage material. We employed "evaporation" process for the synthesis of LiNH 2 (Li-amides) as a candidate of advanced hydrogen storage materials.
