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.
