一维Cu-Zn-Al合金纳米结构的制备

Preparation of One Dimensional Nano-Structures of Cu-Zn-Al Alloy

摘要:

在常温常压下以Cu-Zn-Al合金为基体，用混合酸适当处理，制得了两种不同形貌、结构新颖的一维合金纳米结构。通过透射电子显微镜对它们的形貌和结构进行观察，发现其为中空圆柱结构，接近纳米管，但管壁较厚，中空程度小。根据EDX以及选区衍射确定了产物为一维Cu-Zn-Al合金纳米结构。初步分析了一维Cu-Zn-Al合金纳米结构的形成机理。

Abstract:

In normal temperature and pressure, two kinds of one-dimensional nano-structures with different patterns and structures, whose substrate were Cu-Zn-Al alloy, were successfully prepared after treating by mixed acid. It is found that the products are similar to nanotube because of their hollow and cylindrical structures, but their tube wall is thicker and their inner diameter is thinner than that of typical nanotube. The selected area electron diffraction and EDX analyze is confirm that the products are one-dimensional Cu-Zn-Al alloy nano-structures. The growth mechanics of nano-structures are primarily studied and the growth model is also put forward.
