Direct hydrogen quantification in high-pressure metal hydrides

چکیده
High-pressure metal hydride (MH) research evolved into a thriving field within condensed matter physics following the realization of metallic compounds showing phonon mediated near room-temperature superconductivity. However, severe limitations in determining chemical formula reaction products, especially with regards to their hydrogen content, impedes deep understanding synthesized phases and can lead significantly erroneous conclusions. Here, we present way directly access content MH solids at high pressures (laser-heated) diamond anvil cells using nuclear magnetic resonance spectroscopy. We show that this method be used investigate wide range from x = 0.15 (CuH ) ≲ 6.4 (H 6±0.4 S 5 ).

Hydrogen storage in complex metal hydrides
Complex metal hydrides such as sodium aluminohydride (NaAlH4) and sodium borohydride (NaBH4) are solid-state hydrogen-storage materials with high hydrogen capacities. They can be used in combination with fuel cells as a hydrogen source thus enabling longer operation times compared with classical metal hydrides. The most important point for a wide application of these materials is the reversibil...
متن کاملHydrogen-Mediated Metal Transport in Complex Metal Hydrides
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...
متن کاملAnomalous Behaviour in Hydrogen Diffusion through Palladium and Metal-Hydrides
Hydrogen transport through Pd and metal-hydrides has been usually investigated by using potentiostatic current transient technique (chronoamperometry), on the basis of the diffusion-controlled model. This assumes that hydrogen diffusion in the electrode is very slow, while other reactions including interfacial charge transfer and hydrogen transfer are too fast to influence hydrogen transport, a...
متن کاملHydrogen Absorption/Desorption in Palladium and Metal Hydrides
Electrical generation from hydrogen, the element with higher energy density per unit mass, requires appropriated materials that can be used in its storage [1]. Palladium, with a high capacity to dissociate, absorb and desorb gaseous hydrogen, has been widely used for hydrogen storage [2], in separation membranes [3] and catalytic hydrogenation [4]. The present DFT calculations on clusters model...
متن کاملComplex Metal Hydrides for Hydrogen, Thermal and Electrochemical Energy Storage
Hydrogen has a very diverse chemistry and reacts with most other elements to form compounds, which have fascinating structures, compositions and properties. Complex metal hydrides are a rapidly expanding class of materials, approaching multi-functionality, in particular within the energy storage field. This review illustrates that complex metal hydrides may store hydrogen in the solid state, ac...
