摘要：

The effect of treatment with a fluorine-containing aqueous solution on the hydrogen sorption properties of Mg2Ni has been investigated. The treated Mg2Ni was found capable of being activated and partially hydrided at near room temperature under moderate pressure conditions. Maximum hydrogen capacity after 5 h was about 30% of that of Mg2NiH4, i.e., Mg2NiH1.2. This capacity neither increased nor decreased with repeated hydriding/dehydriding cycles. The F-treatment results in a new fluorinated surface. This new surface exhibits a strong affinity for hydrogen uptake and a higher resistance to impurities.
