| 中文摘要 | 采用异丙醇钛[(C4H9O)4Ti]为先驱体配制二氧化钛溶胶,以阳极氧化铝模板(AAO,孔径尺寸200nm,厚度约60μm)直接浸渍和负压辅助浸渍的方法制备二氧化钛纳米管或管棒混杂的阵列结构,所得产物在450℃下进行热处理后,化学刻蚀去除模板.利用FE-SEM,HR-TEM以及XRD对其微观形貌、结构等进行了观测和分析.结果表明,产物450℃热处理后为多晶锐钛矿相.模板法简单易行,制备出的管棒外径取决于模板孔道的尺寸,在负压辅助下可有效提高产物的连续性.; Titanium dioxide nanotube and nanorod arrays were successfully prepared by the combination of solgel and AAO (anodic aluminum oxide) membrane fabrication. The precursor of titanium dioxide solgel is tetra-isopropyl titanite, and the dipping processing is based on direct dipping or under negative pressure. The products were characterized with FE-SEM, HR-TEM and XRD after heat treatment of samples at 450℃ and removing AAO membranes with NaOH. The results show that the template method is effective in fabricating nanotube arrays, and the products were polycrystalline. The outer diameter of nanotubes is determined by the pore size of template. The pore size and thickness of the membranes used in the experiments were 200 nm and 60 μm respectively. |
