摘要

以含WCl6的无水乙醇溶液为前驱液

PVP为表面活性剂

通过溶剂热法制备了氧化钨纳米线。利用X射线衍射、扫描电镜、透射电镜和选区衍射等手段对制备的纳米线进行了表征

通过调整PVP加入量来调控纳米氧化钨的形貌

并对氧化钨纳米线的生长机制和形貌发生改变的原因进行了分析。

Abstract

Tungsten oxide nanowires were prepared by solvothermal method with the WCl6 as the precursor

the ethanol as the solvent and PVP as the surface activity agent.The nanowires were characterized by X-ray diffraction

scanning electron microscopy

transmission electron microscopy and high-resolution transmission electron microscopy and selected area electron diffraction.Tungsten oxide morphologies were modified through changing the PVP addition.The growth mechanism of tungsten oxide nanowires and the morphology changed were analyzed.
