Enhanced hydrogen storage properties of MgH2 co-catalyzed with NbF5 and single-walled carbon nanotubes
چکیده انگلیسی

The hydrogen storage performance of ball-milled MgH2 with 5 wt.% NbF5 + 5 wt.% single-walled carbon nanotubes as additives was investigated. We found that the hydrogen-sorption kinetics of magnesium is markedly improved by these co-additives. At 573 K, this hydride can absorb 6.3 wt.% hydrogen within 30 s. Even at 373 K, 5.2 wt.% of hydrogen can be absorbed within 10 min. This enhanced hydrogen storage performance was also observed to persist during subsequent absorption/desorption cycles.
