Abstract A novel method for synthesis of titanium oxide (TiO 2 ) nanotubes by microwave irradiation was investigated. Under certain microwave power, TiO 2 nanotubes were gained via the reaction of TiO 2 crystals of either anatase or rutile or mixed phase and NaOH aqueous solution. The products were characterized by—TEM, HRTEM, XRD, BET and ICP. The results showed that the titania nanotubes had the central hollow, open ended and multi-wall structure. The diameters of the nanotubes were 8–12 nm, and the lengths were up to 200–1000 nm. The compositions were titanium and oxygen and the atomic ratio of O/Ti was about 2/1. XRD showed that the titanium oxide nanotubes could be anatase phase.

微波辐射合成二氧化钛纳米管

摘要 研究了一种微波辐射合成氧化钛(TiO 2 )纳米管的新方法。在一定的微波功率下，锐钛矿型或金红石型或混合相的TiO 2 晶体与NaOH水溶液反应得到TiO 2 纳米管。通过TEM、HRTEM、XRD、BET和ICP对产物进行表征。结果表明，二氧化钛纳米管具有中心中空、开口和多壁结构。纳米管的直径为 8-12 nm，长度可达 200-1000 nm。成分为钛和氧，O/Ti的原子比约为2/1。XRD表明氧化钛纳米管可能是锐钛矿相。
