| 英文摘要 | Mg-Y thin films capped with Pd have been prepared by direct current magnetron co-sputtering system. It is found that Mg alloyed with Y in film state forms ultrafine nanocrystalline intermetallic compounds. The structure together with the catalytic effect of Y gives rise to a high electrochemical hydrogen storage capacities and superior activation properties. It is worthy to note that Mg78Y22 film achieves a high discharge capacity of 1590 mAh g(-1) without requiring activation process. Moreover, Mg alloyed with Y effectively improves the cyclic stability of Mg-based films ascribing to the anti-corrosion role of Y. For Mg37Y63 film, more than 92% of the maximum discharge capacity can be maintained after 100 charge-discharge cycles. Copyright (C) 2014, Hydrogen Energy Publications, LLC.
