TLDR
In this article, surface engineering approaches were adopted in the preparation of advanced materials based on AB5 hydride-forming intermetallide, including micro-encapsulation with palladium, as well as with Palladium-containing mixed coatings.Abstract:
Surface engineering approaches were adopted in the preparation of advanced materials based on “low-temperature” AB5 hydride-forming intermetallide. The approaches used included micro-encapsulation with palladium, as well as with palladium-containing mixed coatings. The influence of these modifications on surface morphology and hydro-genation characteristics of the material were investigated. It was found that palladium-nickel encapsulation improves the hydrogenation kinetics of the intermetallide in the absorption of hydrogen at low pressure and room temperature, and after long-term pre-exposure to air. The developed surface-modified materials may potentially find their application in highly-selective hydrogen extraction and purification processesread more

The palladium hydrogen system
Abstract: A wide ranging survey is presented updating information and opinions on the correlations which occur between structural change and hydrogen pressure-hydrogen content-temperature (p -c (n ) T ) relationships in the palladium-hydrogen and other related systems. Particular attention is directed to problems of the estimation and definition of the limits of composition over the a t;, pphase transition region and near to designated critical points.
