Mg含量大于90 at.%的Mg-Ce-Ni非晶合金都是捏造的值得注意的是，该金属玻璃可以可逆地吸收和解吸约0.2-0.4wt.%-在室温下，未活化的镁基合金的吸氢能力为晶态合金的2倍。结果表明，合金的贮氢能力与其非晶结构密切相关，Mg含量越高的非晶结构贮氢能力越强。该工作为金属玻璃介质储氢提供了一种新的途径。
Mg–Ce–Ni metallic glasses with record high Mg content larger than 90at.% were fabricated. Remarkably, the metallic glasses can reversibly absorb and desorb about 0.2–0.4wt.%-H at room temperature without activation, and the hydrogenation capacity of the glassy Mg-based alloy is twice larger than that of the corresponding crystalline alloy. It is found that hydrogenation capacity shows close connection with the glassy structure of the alloys, and the higher Mg content amorphous structure can store more hydrogen. The work might present a way for gaseous hydrogen storage by metallic glasses media.
