摘　　要：利用金属Mg易热扩散制合金的特性,以化学镀Ni的碳纳米纤维(Ni-CNFs)为前驱物,制备出了Mg-Ni合金与CNFs的复合储氢材料.并测试了其电化学性能,提出了镁基储氢合金与CNFs复合储氢材料的储氢机理.As magnesium can be alloyed with other metals easily, a kind of composite hydrogen storage material of Mg-Ni alloy with carbon nanofibers(CNFs) is prepared by thermal diffusion with electroless nickel plated carbon nanofibers(Ni-CNFs) as precursor. The electrochemical performance of this composite hydrogen storage material is tested, while its mechanism of hydrogen storage is proposed.$$$$
