“…Thus, the absorption time to reach the hydrogen saturation in the second and third cycle for Mg 65 Cu 10 Al 15 MM 10 alloy is lower than for the Mg 65 Cu 25 MM 10 alloy. The absorption time is observed to decrease from the second to the third cycle for both alloys, which is in agreement with a general behaviour of H-sorption properties in Mg alloys 31,32 .…”

“…These alloys were tested to three consecutive cycles of hydrogen absorptiondesorption. It was found that the rate of the first absorption cycle (activation) is low, which is usual for Mg alloys 31 . The sluggish rate during the activation cycle can be related to the presence of an oxide layer on the surface of the sample, which must be broken to start the hydrogenation through the volume of the material 4 .…”

In this paper we report the effect of alloying elements on hydrogen storage properties of meltspun Mg-based alloys. The base alloys Mg 90 Si 10 , Mg 90 Cu 10 , Mg 65 Cu 35 (at%) were studied. We also investigated the effect of rare earths (using MM: mischmetal) alloys showed an amorphous and partially amorphous structure respectively. At 350˚C all the alloys had a crystalline structure during the hydrogen absorption-desorption tests. It was observed that Si and Cu in the binaries alloys hindered completely the activation of the hydrogen absorption. The partial substitution of Cu by MM or Al allowed activation. The combined substitution of Cu by MM and Al showed the best results with the fastest absorption and desorption kinetics, which suggests that this combination can be used for new Mg-alloys to improve hydrogen storage properties.

“…After 10 cycles, 90% of the total capacity is absorbed within 10 seconds, which is similar to what was observed for other Mg-TM cosputtered films. 9 Hydrogen sorption measurements cannot distinguish the individual contributions of surface dissociation, diffusion and phase transformation to the 'overall' kinetics. Therefore, an in situ technique with high spatial resolution is required to separate bulk (diffusion, nucleation) and surface (dissociation) effects in real-time.…”

“…Among these additives, some transitional metals (Barkhordarian et al 2003;Czujko et al 2006), their oxides (Mao et al 2010) and halides (Ma et al 2009) provide good catalytic effects. Since a single additive does not provide enough catalytic power (Kalisvaart et al 2010), several additives working together improve the materials' hydrogen storage abilities, with promising results . Adding binary catalysts to Mg is a hot topic, while ternary catalysts in Mg are rarely reported.…”
