Název v původním jazyce

Hydrogen storage behavior of Mg@Mg2Si and Mg@Mg17Al12 alloys with additions of carbon allotropes and talc

Popis výsledku v původním jazyce

Mg based hydrogen storage alloys containing catalyzing particles are frequently studied because thencatalysis is one of possible ways how to speed-up effectively the hydrogen sorption kinetics. Ball millednalloys Mg@Mg 2 Si and Mg@Mg 17 Al 12 are studied in the present paper. They consist of Mg grains, whichnhydrogen storage performance is catalyzed by the Mg 2 Si and Mg 17 Al 12 particles. Graphite, amorphousncarbon (carbon black) and magnesium silicate monohydrate (talc) were added to facilitate the fine ballnmilling. It was found that addition 0.14 wt% of amorphous carbon to Mg@Mg 2 Si shows the best hydrogennsorption kinetics and the highest sorption capacity of about 6 wt% H 2 . A weak destabilization of MgH 2nhydride by Mg 2 Si and Mg 17 Al 12 was observed. New technique of equilibrium hydrogen pressure esti-nmation was proposed.
