    摘要:

    采用溶膠-凝膠法在納米孔氧化鋁模板上成功制備形貌各異的WO3納米線。X射線衍射分析表明所制備的WO3納米線為立方相結(jié)構(gòu)。經(jīng)掃描電子顯微鏡觀察發(fā)現(xiàn)產(chǎn)物多數(shù)為菊花狀WO3納米線，其直徑約10~80 nm，長約幾微米。與空氣氣氛相比，氬氣氣氛更有助于WCl6三嵌段共聚物溶膠在多孔氧化鋁模板上形成形貌各異的WO3納米線。

    Abstract:

    WO3 nanowires with various morphologies were prepared on nanoporous alumina template by a simple sol-gel method. X-ray diffraction analysis reveals that the obtained materials are cubic WO3. Scanning electron microscopy shows that the products contain chrysanthemum-shaped WO3 nanowires. The diameter of WO3 nanowires is about 10-80 nm and their length is up to several micrometers. Argon gas atmosphere is more favorable for WCl6-triblock copolymer sol to form WO3 nanowires with different morphologies on nanoporous alumina template than air atmosphere.
