利用配位反应法制备多孔阳极氧化铝/氧化锌纳米线阵列

Preparation of Porous Anodic Alumina/Zinc Oxide Nanowire Arrays by a Coordination Reaction Method

研究了一种新型的制备氧化锌(ZnO)纳米线的配位反应法。以氨水为配位剂、氨水与可溶性的锌盐反应配制的锌氨配合物溶液为前驱液,在多孔阳极氧化铝(porous anodic alumina,PAA)模板中沉积了ZnO纳米线。研究了ZnO纳米线的生长机理和配位反应条件。用X射线衍射仪、扫描电子显微镜和透射电子显微镜对PAA/ZnO组装体的组成和形貌进行了表征。结果表明:所制备的ZnO纳米线为多晶结构,纳米线阵列具有周期排列结构,与多孔氧化铝模板形态特征一致。

A novel method named ＂coordination reaction method＂ was developed to fabricate zinc oxide（ZnO） nanowire arrays.The ZnO nanowires in the holes of the porous anodic alumina（PAA） template were synthesized with ammonia as a coordination agent and zinc-amino complex as a precursor by the coordination reaction method.The growth mechanism of ZnO nanowires and the condi-tions of the coordination reaction were also discussed.The microstructures and morphology of PAA/ZnO assembly were characterized by X-ray diffractometer,scanning electron microscope and transmission electron microscope.The results show that the ZnO nanowires prepared are a polycrystalline structure,and the nanowire arrays possess a periodic array of structure with the same morphological characteristics of PAA template.
