用TiO2粉末、NaOH和蒸馏水为原料合成金红石型TiO2纳米棒。XRD和FESEM分析表明,制备的样品为单晶且无杂质,其平均粒径约为40 nm。当样品于600°C退火2 h后,FESEM观察发现生成了TiO2纳米棒。XRD分析表明纳米棒为单晶。纳米棒表面光滑,其长约为1μm,直径约为80 nm。紫外和拉曼光谱研究表明,所制备样品的能带间隙为3.40 eV。 The TiO2 powder, NaOH and distilled water were used as raw materials to synthesize rutile TiO2 nanorods. XRD and FESEM analysis showed that the prepared samples were single crystal and without impurities, the average particle size was about 40 nm. After the samples were annealed at 600 ° C for 2 h, FESEM observations revealed the formation of TiO2 nanorods. XRD analysis shows that the nanorods are single crystal. The surface of the nanorods is smooth and has a length of about 1 μm and a diameter of about 80 nm. UV and Raman spectroscopy studies showed that the prepared band gap was 3.40 eV.
