Hydrogen sorption characteristics of the composites 90 wt.% Mg (MgH2)–10 wt.% V0.855Ti0.095Fe0.05

FCC/α-Fe biphasic nano-sites synergize with CNTs to enhance reversible hydrogen storage of MgH2

“…In addition, ternary VTiFe alloys have been demonstrated to exhibit excellent performance in hydrogen storage and in enhancing the reversible kinetics and cyclic stability of Mg/MgH 2 . 4,10,42 Furthermore, a recent study highlighted the effectiveness of the TiVNbCr alloy in improving the hydrogen storage kinetics of MgH 2 . 43 These catalysts exhibit high catalytic activity due to optimized electronic structural features and synergistic catalytic effects, which significantly enhance the de-/hydrogenation kinetics of Mg/MgH 2 .…”

Catalytic effect of (Ti0.85Zr0.15)1.05Mn1.2Cr0.6V0.1Cu0.1on hydrogen storage properties of ultrafine magnesium particles

“…19 Aer ball milling for 5 hours, the Mg-V 0.855 Ti 0.095 Fe 0.05 composite presented a rapid hydrogen sorption rate, which was able to uptake 4.97 wt% H 2 at 573 K within 60 min and release 5.5 wt% hydrogen at 623 K within 40 min. 20 Among the hydrogen storage alloys, the TiMn 2 type alloys 21 with excellent hydrogen storage properties at room temperature are seldom studied as an additive for Mg-based hydrogen storage material, let alone the consideration of their content on the performance of Mg.…”

Hydrogen Desorption Properties of Mechanically Alloyed MgH₂-9 wt % V-1 wt% Al Nanocomposite

“…So far, numerous works have been made to overcome these barriers from alloying magnesium hydride with other elements or mixing it with catalysts to reduction of crystallite and particle size and formation of defects in the metallic crystal structure [8]. Recently, mechanical alloying has been used for solid state fabrication of nanocrystalline materials as the process offers significant grain refinement with an increase in specific surface area and structural defects [9]. Among the transition metals, Vanadium has been widely used because of the best catalytic properties for desorption hydrogen [10].…”
