采用溶胶-凝胶法在纳米孔氧化铝模板上成功制备形貌各异的WO3纳米线.X射线衍射分析表明所制备的WO3纳米线为立方相结构.经扫描电子显微镜观察发现产物多数为菊花状WO3纳米线,其直径约10～80 nm,长约几微米.与空气气氛相比,氩气气氛更有助于WCl6三嵌段共聚物溶胶在多孔氧化铝模板上形成形貌各异的WO3纳米线.

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.
