The effects of Ni and Mg2Ni interlayer on hydrogenation properties of Pd sandwiched Mg films

An overview of progress in Mg-based hydrogen storage films*

“…They found that the addition of the appropriate amount of Al can promote the hydrogenation of the Mg layer as an activator, thereby improving the hydrogen storage capacity. But they also found that the addition of Al did not significantly reduce the desorption temperature compared to Pd/Mg/Pd films, with a desorption temperature around 403 K-413 K. Jain et al [102] prepared Pd/Mg/Ni/Pd and Pd/Mg/Mg 2 Ni/Pd films with the Pd/Mg/Pd base system using vapor deposition and found that Pd/Mg/Ni/Pd and Pd/Mg/Mg 2 Ni/Pd films absorb 7.08 × 10 17 and 1.68 × 10 18 hydrogen atoms/cm 2 , respectively, in comparison to 4 × 10 17 atoms/cm 2 absorbed by the base system. They contributed the high hydrogen content to the formation of additional hydrogen absorption phase in interlayers of Ni and Mg 2 Ni.…”

Excellent hydrogen sorption kinetics of thick Mg–Pd films under mild conditions by tailoring their structures

“…6,7 Compared with the bulk material, Mg thin films are reported to absorb/desorb hydrogen at relatively low temperature. [8][9][10][11][12][13][14] Moreover, the composition, interface and crystallinity of thin films can be accurately tailored on the nanoscale. 15 Studies also demonstrate that the hydrogen storage properties of Mg films can be significantly improved by their alloying with 3d-transition metals.…”
