摘要/Abstract

摘要： 使用高纯铝箔作为初始原料，以多孔阳极氧化铝模板为中间产物，通过对多孔阳极氧化铝模板进行水热反应的方法制备出勃姆石（γ-AlOOH）纳米线，产物的特征长度为60 nm，直径在2～5 nm之间。整个实验方法简单，且没有引入其他杂质元素。分析了反应过程及水热反应温度和时间对勃姆石纳米线形貌的影响，并通过对比实验表明AAO模板的纳米多孔结构是水热反应生成勃姆石纳米结构的必要条件和主要原因。

Abstract: High purity alumina foils were used as raw material. Based on porous anodic aluminium oxide membrane (AAO), the pivotal intermediate product, boehmite nanowires were successfully synthesized by an efficient hydrothermal method. The whole reaction process was very simple and avoids the superfluous impurities. The characteristic length of the products was 60 nm and the diameter of them is about 2-5 nm. By the comparative experiments, it could be concluded that the multiporous structure of AAO was the key reason for synthesizing boehmite nanowires by this method.

Key words: boehmite nanowires, anodic aluminum oxide template, hydrothermal method
