摘要

The present study reports the effect of Ni addition on the structure and hydrogen storage properties of Mg₁₇Al₁₂ alloy. The Mg ₁₇Al₁₂ is synthesized by conventional melting process, and then ball-milled with Ni powder to form Mg₁₇Al₁₂-X wt.% Ni (X = 0, 10, 20) alloys. XRD results showed that the formation of stable Al₃Ni and Al₃Ni₂ phases in the Ni-containing alloys after hydrogenation results in the production of surplus Mg during the desorption process. The catalytic effect of surplus Mg on the Ni-containing alloy is responsible for an enhancement of the hydrogen capacity and absorption rate, compared with ball-milled Mg₁₇Al₁₂ below 300 °C.
