摘要

在含有低浓度离子液体（EMim.BF4，0.6-1.6体积%）的乙二醇电解质中，通过阳极氧化研究了钨上的介观结构WO3膜。可以通过改变阳极氧化的时间、电势和温度以及电解质中离子液体和水的浓度来调节所制备的WO3膜的表面结构。分别用X射线衍射仪（XRD）和场发射扫描电子显微镜（SEM）对样品进行了表征。在优化的参数下可以获得自组织的介观结构WO3。该介观结构的WO3膜被排列成平均颗粒直径为30nm的阵列的部分。

Preparation of tungsten trioxide film with mesoporosity by anodisation

The mesostructured WO3 film on tungsten was investigated by anodic oxidation in ethylene glycol electrolytes containing low concentrations of ionic liquids (EMim.BF4, 0.6-1.6 vol. %). The surface structure of the WO3 film as prepared can be adjusted by changing the time, potential and temperature of anodisation, and the concentration of ILs and water in the electrolyte. The sample was characterised by X-ray diffraction (XRD) and field-emission scanning electron microscope (SEM) respectively. A self-organised mesostructured WO3 can be obtained under optimised parameters. The mesostructured WO3 film is arranged in sections of arrays with an average granular diameter of 30 nm.
