Leilly、Rudmen和本研究组分别对Mg_2Ni-xMg,Mg_2Cu-xMg体系进行了研究,巳发现Mg_2Ni或Mg_2Cu的存在对镁的氢化,释氢过程有催化作用,并描述了二元合金Mg_2Ni,Mg_2Cu对Mg的吸、放氢过程的催化氢化、脱氢模型。但有关三元合金对纯镁的吸、放氢催化性能研究,至今未见报道。我们合成了在基质镁粒表面包覆Mg_2Ni_(0.75) Cu_(0.25)的新型材料,并研究此三元合金表面对所包覆的Mg核与H_2之间反应的影响。
Leilly, Rudmen and the research group respectively studied Mg2Ni-xMg and Mg2Cu-xMg systems. It has been found that the presence of Mg2Ni or Mg2Cu has a catalytic effect on the hydrogenation and dehydrogenation of magnesium. The binary Mg2Ni and Mg2Cu pairs Adsorption and Desorption of Mg, Hydrogenation and Dehydrogenation. However, there is no report on the catalytic performance of ternary alloys for absorption and desorption of pure magnesium. We synthesized a new type of Mg2Ni_ (0.75) Cu_ (0.25) coating on the surface of Mg matrix and studied the effect of the ternary alloy surface on the reaction between Mg core and H_2.
