I have had thoughts on the hydrides possible for B, C, N, O & F, and particularly for N there seems to be some interesting undiscovered possibilities. Thus I am aware of: (1) the hydrides of B have been investigated & elucidated by Stock et al. and Lipscomb et al. & I have tried to read this literature, but I am not able to get a reliable source, and I understand that the hydrides of B differ f...

For the continuous production of electricity with solar heat power plants the storage of heat at a temperature level around 400 degrees C is essential. High temperature metal hydrides offer high heat storage capacities around this temperature. Based on Mg-compounds, these hydrides are in principle low-cost materials with excellent cycling stability. Relevant properties of these hydrides and the...

Observation of high-temperature superconductivity in compressed sulfur hydrides has generated an irresistible wave of searches for new hydrogen-containing superconductors. We herein report the prediction of high-T_{c} superconductivity in tellurium hydrides stabilized at megabar pressures identified by first-principles calculations in combination with a swarm structure search. Although telluriu...

It has recently been shown that Severe Plastic Deformation (SPD) techniques could be used to obtain nanostructured metal hydrides with enhanced hydrogen sorption properties. In this paper we review the different SPD techniques used on metal hydrides and present some specific cases of the effect of cold rolling on the hydrogen storage properties and crystal structure of various types of metal hy...

The most important unsolved problem for the introduction of the Hydrogen Economy is efficient and safe storage of hydrogen. Alanates, compounds based on the AlH4 unit, are among the most promising metal hydrides for reversible hydrogen storage. The storage capacity is large, e.g. NaAlH4 can release 5.6 wt% hydrogen below 200 C. Work during the last years has revealed that Ti additives improve t...

Since this discovery, a number of studies have looked at improving the catalytic effects and understanding the role of additives in H2 cycling. However, the mechanism by which NaAlH4 is activated in the presence of a small amount of a transition metal is still not well understood. One of the principle questions is “How do the Al atoms migrate the long distances required during the hydrogenation...

The phase stability diagrams for the decomposition of magnesium alanate [Mg(AlH4)2] nanoparticles were constructed as a function of particle size and temperature to better understand nanostructuring of the complex hydrides for hydrogen storage. Relatively smaller nanoparticles of Mg(AlH4)2, MgH2, Al, and Mg ranging from 1 to 2 nm were directly calculated by using density functional theory (DFT)...
