摘要

用合成金红石制备独立纳米线，在500℃下用NaOH处理4小时，然后反复水洗[1-5]。样品再用40%和50%的NaOH(浸出法)处理。这是形成线材结构的关键部分。该工艺已生产出直径在20 ~ 30nm、长度在4µm以上的金属丝。用x射线衍射(XRD)和扫描电镜(SEM)对产物进行了表征。提出了合成金红石前驱体制备纳米管的可能机理。

Synthesis of TiO2 nanowires from fusion method

Free standing nanowires were produced from synthetic rutiles which were treated with NaOH at 500°C for 4 hours, followed by repeated water washing [1–5]. The samples had been treated again with 40% and 50% of NaOH (leaching process). This is the critical part of forming the wire structure. Diameter of the wires from 20–30nm and length of more than 4µm had been produced from this process. Products were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). A possible formation mechanism of nanotuwires from synthetic rutiles precursor is proposed.
