EFFECT OF SiC ADDITION ON HYDROGEN DESORPTION PROPERTIES OF NANOCRYSTALLINE MgH2 SYNTESIZED BY MECHANICAL ALLOYING
In this study, the composite material with composition of MgH2-5 wt% SiC has been prepared by co-milling of MgH2 with SiC powder. The effect of milling time and additive on MgH2 structure, i.e. crystallite size, lattice strain, particle size and specific surface area, and also hydrogen desorption properties of obtained composite was evaluated by thermal analyzer method and compared with pure un...
متن کاملEffect of Milling Time on Hydrogen Desorption Properties of Nanocrystalline MgH2
Nanocrystalline magnesium hydride powder was synthesized by mechanical milling of MgH2 in a planetary ball mill for various times. The effect of MgH2 structure, i.e. crystallite size, lattice strain, particle size and specific surface area on the hydrogen desorption properties was investigated. A single peak of hydrogen desorption was observed for as-received powder, exhibiting an average parti...
متن کاملHydrogen Desorption Properties of Nanocrystalline MgH2-10 wt.% ZrB2 Composite Prepared by Mechanical Alloying
Storage of hydrogen is one of the key challenges in developing hydrogen economy. Magnesium hydride (MgH2) is an attractive candidate for solid-state hydrogen storage for on-board applications. In this study, 10 wt.% ZrB2 was co-milled with magnesium hydride at different milling times to produce nanocrystalline composite powder. The effect of milling time and additive on the hydrogen desorption...
متن کاملEffect of transition-metal additives on hydrogen desorption kinetics of MgH2
Using first-principles calculations, we study the effect of transition-metal additives (Ti, Fe, Co, and Ni) on the rate of hydrogen desorption in MgH2. The presence of large concentrations of transition-metal impurities causes the Fermi level to shift according to the position of the transition-metal acceptor/donor levels in the band gap. This shift can lower the formation energy of native defe...
