Magnesium-based hydrogen storage nanomaterials prepared by high energy reactive ball milling in hydrogen at the presence of mixed titanium–iron oxide

Nanostructured hydrogen storage materials prepared by high-energy reactive ball milling of magnesium and ferrovanadium

“…S14. As distinct from previously studied HRBM Mg, Mg C [10] and Mg FeTiO 3 [12] composites exhibiting noticeable agglomeration of submicron particles, the agglomeration in the samples studied in this work was less pronounced. Introduction of carbon (see example for Mg-10(FeV)-5MWCNT in Fig.…”

“…The most efficient way to overcome these drawbacks is in a use of nanocomposite materials by employing reactive ball milling of Mg in hydrogen atmosphere (HRBM; see Refs. [8][9][10][11][12][13][14] and references therein) in presence of catalytic additives. Particularly strong catalytic influence was observed for the additives of vanadium metal/V-based alloys.…”

Superior Hydrogen Absorption–Desorption Cycle Durability of Ball‐Milled 82MgH2‐3PrH2‐15Al Composite

“…Generally, the property degradation of Mg‐based hydrogen storage materials during cycling is related to partially irreversible loss of hydrogen storage capacity and deterioration of hydrogen sorption kinetics . The origins of degradation include crystallite growth and powder agglomeration of Mg, coarsening, redistribution and invalidation of catalysts, oxidation of Mg/MgH 2 , and so on during hydrogen absorption and desorption cycling. Following this idea, the Ni‐catalyzed MgH 2 /GNs (graphene nanosheets) system was developed, showing good cycle durability because GNs can provide more hydrogen diffusion channels, inhibit crystallite growth and prevent Mg/MgH 2 from oxidizing …”
