一种Cr3Al纳米线的制备方法
摘要：
本发明公开了一种Cr3Al纳米线的制备方法，该方法是采用多孔阳极氧化铝(AAO)模板结合电化学沉积法,以Al2(SO4)3·7H2O、Cr2(SO4)3·6H2O、H3BO3和抗坏血酸的混合液为电镀液，并调节电镀液pH值为2.5～3.5，电镀生长后刻蚀掉模板，制备得到Cr3Al纳米线阵列。本发明的方法采用简单的电化学沉积工艺，通过对电镀液的选择及生长参数的调节，首次实现了在多孔阳极氧化铝的柱形微孔内制备铬三铝合金磁性纳米线有序阵列。
摘要（英）：

The invention discloses a preparation method for Cr3Al nanowires. The preparation method comprises the steps that a porous anodic aluminum oxide (AAO) template is combined with an electrochemical deposition method; mixed liquid of Al2(SO4)3.7H2O, Cr2(SO4)3.6H2O, H3BO3 and ascorbic acid serves as electroplate liquid; the pH value of the electroplate liquid is adjusted to be 2.5-3.5; and after electroplating grows, the template is etched, so that Cr3Al nanowire arrays are prepared. According to the preparation method for the Cr3Al nanowires, the simple electrochemical deposition process is adopted, and the Cr3Al alloy magnetic nanowire ordered arrays are prepared in porous anodic aluminum oxide cylindrical micro holes for the first time through selection and growth parameter adjustment of the electroplate liquid.
