Excellent catalytic effects of multi-walled carbon nanotube supported titania on hydrogen storage of a Mg-Ni alloy.

Superior catalytic effects of multi-walled carbon nanotube supported titania synthesized by the sol-gel method on hydrogen storage of a Mg-Ni alloy were investigated. The excellent hydrogen storage properties were obtained: absorbed 5.60 wt% H2 within 60 s at 373 K and released 6.08 wt% H2 within 600 s at 553 K.
