Enhanced hydrogen sorption properties of Ni and Co-catalyzed MgH2

NbCl5 and CrCl3 catalysts effect on synthesis and hydrogen storage performance of Mg–Ni–NiO composites

“…Mg provides high hydrogen storage capability, while additives act as catalysts to improve the rate of hydrogen absorption and desorption and decrease the hydrogen storage temperature. Among these additives, some transitional metals (Barkhordarian et al 2003;Czujko et al 2006), their oxides (Mao et al 2010) and halides (Ma et al 2009) provide good catalytic effects. Since a single additive does not provide enough catalytic power (Kalisvaart et al 2010), several additives working together improve the materials' hydrogen storage abilities, with promising results .…”

Hydrogen Absorption at a Low Temperature by MgH2 after Reactive Mechanical Grinding

“…Mao et al 19) 22) dealt with non-isothermal kinetics models of hydrogen desorption from MgH 2 altered by ion bombardment and stressed the importance of the MgH 2 surface during its decomposition. The concentration and good dispersion of defects in nearsurface region were important factors.…”

NiB nanoparticles: A new nickel-based catalyst for hydrogen storage properties of MgH2

“…Yang et al [23] investigated effects of Ni particles of different sizes on hydrogen desorption of MgH 2 , they found that the sorption properties of the MgH 2 mainly depend on the site density of catalytic particles. Mao et al [24] reported that the improved dehydrogenation temperature and sorption kinetics of MgH 2 doped with NiCl 2 or CoCl 2 , the additives reduced the barrier and lowered the driving forces for nucleation, thus promoting the sorption properties of NiCl 2 and CoCl 2 catalyzed magnesium hydride.…”
