Abstract
The influence of hydrogen on a (Co0·2Cu0·2Mg0·2Ni0·2Zn0.2)O HEO with a rock salt structure was studied. Two forms of this HEO (nanopowder and sinter) were prepared via mechanochemical synthesis (MS) and additional heat treatment, respectively. The chemical stability of the synthesized samples in a pure hydrogen atmosphere was investigated using Sievert's technique. High-pressure hydrogenation at 250 °C had no noticeable effect on the HEO sinter. The sintered sample was chemically, structurally, and morphologically stable, as confirmed via the XRD, Raman spectroscopy, SEM, and XPS techniques. Thermogravimetric analysis (TGA) showed the sinter to be stable in an argon gas mixture with 5 vol% of hydrogen and over the temperature range of up to 400 °C. © 2023 Elsevier Ltd and Techna Group S.r.l.
