| 摘 要： | 利用磁控溅射法制备了两组Mg/Nb复合薄膜,研究了不同Nb层厚度和不同基底温度对Mg/Nb复合薄膜脱氢温度的影响。结果表明,当Nb层厚度为1nm和2nm时,其催化效果相对最好,可使Mg/Nb复合薄膜的脱氢温度分别降至110℃和122℃。当基底温度为125℃时对脱氢性能的改善效果最佳,可使Mg(100nm)/Nb(1nm)复合薄膜的脱氢温度降至100℃。同时,讨论了Nb层厚度和基底温度对Mg/Nb复合薄膜脱氢温度的影响机制。

| Abstract: | Two groups of Mg/Nb composite films were prepared by magnetron sputtering.The effects of Nb layer thicknesses and substrate temperature of Mg/Nb composite films on the dehydrogenation temperatures were investigated.Results showed that the Nb layers with thicknesses of 1 nm and 2 nm exhibited the superior catalytic effects,which can lower the dehydrogenation tem-peratures to 110 ℃ and 122 ℃,respectively.Besides,the substrate temperature of 125 ℃ during sputtering presented the vastest en-hancement to the dehydrogenation performance of Mg (100 nm)/Nb (1 nm)composite film.The dehydrogenation temperature could decrease to 100 ℃.Meanwhile,the relative mechanisms and the effects of Nb layer thicknesses and substrate temperatures of Mg/Nb composite thin films on their dehydrogenation temperatures were discussed. |
