通过简单的溶液反应，在60 ℃下由配合物[Fe（phen）（3）]（2+）制备了自支撑的定向排列的β-FeOOH纳米线图案。直径为40 nm，长度为6 μ m的纳米线的排列相对均匀。HRTEM研究表明，β-FeOOH纳米线的生长方向垂直于自形成的片状β-FeOOH基片的取向面。在反应和晶体生长过程中，前驱体[Fe（phen）（3）]（2+）无疑对纳米线取向的形成至关重要。详细地说，排列的纳米线的形成被认为是通过控制两个竞争反应来实现的。电化学和紫外-可见光谱测试表明，该产物在锂电池和半导体电子领域具有潜在的应用价值。该合成过程简单、温和、清洁、可重复，且不含任何模板;它为纳米线的低温生长及其同时定向排列提供了一种新途径。
Self-supported patterns of oriented alignment of beta-FeOOH nanowires are fabricated through a simple solution reaction from the complex [Fe(phen)(3)](2+) at 60 degrees C. The alignment of nanowires with a diameter of 40 nm and length of 6 mum is relatively uniform. HRTEM studies show that the growing direction of beta-FeOOH nanowires is perpendicular to the orientation plane of self-formed beta-FeOOH flake-like substrates. In the reaction and crystal growth process, the precursor [Fe(phen)(3)](2+) is undoubtedly vital to the formation of nanowire alignment. In detail, the formation of aligned nanowires is thought to be realized by controlling two competing reactions. Electrochemical and UV-visible measurements suggest that the product might have potential applications in lithium batteries and semiconductor electronics. This synthetic process is simple, mild, clean, reproducible, and free of any template; it provides a novel pathway for the low-temperature growth of nanowires and their simultaneous oriented alignment.
