利用微波水热法,以TiC l3为前驱物,成功地制备了金红石相的TiO2纳米棒。在特定的反应条件下,这些纳米棒自发聚集成大面积的取向阵列。纳米棒的平均直径约50 nm,而且从扫描和透射电镜分析可知,它们是由约5 nm的纳米线组成的。利用电子背散射衍射技术(EBSD),对该样品中纳米棒的晶体学取向进行了研究,进而对生长机理进行了讨论。
The rutile TiO2 nanorods were successfully prepared by microwave hydrothermal method and TiC13 as precursors. Under certain reaction conditions, these nanorods spontaneously aggregate into large-area oriented arrays. The nanorods have an average diameter of about 50 nm, and from scanning and transmission electron microscopy analyzes, they are composed of nanowires of about 5 nm. The electron backscatter diffraction (EBSD) was used to study the crystallographic orientation of the nanorods in this sample, and the growth mechanism was discussed.
