Structure transformations and hydrogen storage properties of co-sputtered MgNi films

Morphologic, Structural, Steric, Energetic and Thermodynamic Studies of the Mechanical Alloy Mg50Ni45Ti5 for Hydrogen Storage

“…Also the existence of Ni would decrease significantly the discharge capacity of the alloy as the Ni is not a hydrogen storage element [19]. In accordance to the forgoing, the mechanical milling alloy Mg 50 Ni 45 Ti 5 has a high oxygen sensibility so it shares a good affinity to hydrogen [20]. We can say from the results of XRD and SEM that the powder of Mg 50 Ni 45 Ti 5 is a good candidate to the storage of hydrogen.…”

“…We can say from the results of XRD and SEM that the powder of Mg 50 Ni 45 Ti 5 is a good candidate to the storage of hydrogen. The nanocrystalline nature improves the hydrogen absorption properties, in cooperation with the hydrogen diffusion along with the grain boundaries [20]. Not only that but also there is a critical factor for hydrogen absorption which is basically the composition of the metal.…”

“…In addition, the nanosized metal particles leading to extra hydrogen absorption [29]. However, this parameter is inhibited by impurities in the milling atmosphere, particularly the oxidation, like for example, the TiO 2 and NiO 2 ( Figure 3) [19,20]. This latter may explain the slightly decrease in the total saturation absorption quantity per unit formula.…”

Analysis of Hydrogen in Inorganic Materials and Coatings: A Critical Review

“…Analysis of hydrogen and deuterium by ERDA in oxide layers on nickel alloys was described in [83]. Analyses of hydrogen in metallic layers by ERDA have also involved, e.g., Al/Cu/Ag/Au multilayers [101], Mg/Ni films [102,103], and Fe/Ti films [104].…”

Hydrogen sorption in crystalline and amorphous Mg–Cu thin films

“…Mg [6], Mg-Nb [7] and Mg-Ti [8] crystalline films as thick as 20-30 m have been deposited with absorption and desorption characteristics that are very similar to those reported for bulk-or powder-processed Mg-based alloys. Pranevicius et al [9] sputter deposited amorphous Mg-Ni films of 1.5 m thickness onto quartz substrates, but have not reported data regarding its desorption characteristics. Most thin film studies of relevance that are reported in literature are in the thickness range of 200-1000 nm [10][11][12][13][14][15][16][17][18][19][20][21][22].…”
