摘　　要：利用四氯化钛作钛源,采用简单的微乳液方法合成了超细TiO_2纳米棒。采用X射线衍射仪和透射电子显微镜对产物进行了表征。实验结果表明:所得的超细TiO_2纳米棒为金红石型,直径小于5 nm。该纳米棒对亚甲基蓝的降解有好的光催化活性。这种超细TiO_2纳米棒有望成为一种新型的光催化剂而用于水处理以及空气净化中。Ultrafine TiO2 nanorods were synthesized using titanium tetrachloride（TiCl4） as titanium source by a simple microemulsion method.The obtained product was characterized by X-ray diffraction and transmission electron microscopy.The experimental results showed that the obtained ultrafine TiO2 nanorods were rutile phase,and the TiO2 nanorods had a diameter of less than 5 nm.The obtained ultrafine TiO2 nanorods had good photocatalytic activity for degradation of methylene blue. The ultrafine TiO2 nanorods are expected to become a new type of photocatalyst for water treatment and air purification.
