Composite hydrogen storage material of hydrogen storage alloy/carbon nanotube and producing method thereof

摘要

The present invention relates to a composite hydrogen storage material, which contains hydrogen storage alloy and carbon nanotube, wherein content range of the hydrogen storage alloy is 1-90 % by weight, said hydrogen storage alloy is one or more of rare earth metal-nickel system AB5 type, zirconium base, titanium base or rare earth metal-nickel base Laves-phase system AB2 type, titanium-nickel or titanium-iron system AB type, magnesium base alloy A2B type or amorphous alloy. The present invention also relates to a method for producing the hydrogen storage alloy, which is the method of catalytic cracking or mechanical complex. The composite hydrogen storage material of the present invention has high capacity, property stability and wide use.
