catalysis is one of possible ways how to speed-up effectively the hydrogen sorption kinetics. Ball milled
alloys Mg@Mg 2 Si and Mg@Mg 17 Al 12 are studied in the present paper. They consist of Mg grains, which
hydrogen storage performance is catalyzed by the Mg 2 Si and Mg 17 Al 12 particles. Graphite, amorphous
carbon (carbon black) and magnesium silicate monohydrate (talc) were added to facilitate the fine ball
milling. It was found that addition 0.14 wt% of amorphous carbon to Mg@Mg 2 Si shows the best hydrogen
sorption kinetics and the highest sorption capacity of about 6 wt% H 2 . A weak destabilization of MgH 2
hydride by Mg 2 Si and Mg 17 Al 12 was observed. New technique of equilibrium hydrogen pressure esti-
mation was proposed.Pracoviště Ústav fyziky materiálu Kontakt Yvonna Šrámková, sramkova@ipm.cz, Tel.: 532 290 485 Rok sběru 2019
