三氧化钨的制备及其在水处理中的应用

Preparation of Tungsten Trioxide and Its Application in Water Treatment

以钨酸盐和十二烷基苯磺酸为原料,通过使用简单的溶剂热法来制备WO3纳米材料,并利用扫描电子显微镜、X-射线衍射和透射电镜等手段进行表征,同时研究不同条件下所得产物的形貌、粒径、晶型以及结构等特点。实验结果显示,当制备产物的前驱体不同时,得到的产物形貌和粒径不同。当改变溶剂的水醇比时,随着溶剂中乙醇量的减少,产物的形貌变化明显。

WO3 nanomaterials were prepared by a simple solvothermal method with tungstate and dodecylbenzenesulfonic acid as raw materials.The as-synthesized samples were characterized by scanning electron microscopy(SEM),X-ray diffraction(XRD)and transmission electron microscopy(TEM).Meantime,the morphology,particle size,crystal structure and structure characteristics of the as-obtained product were investigated under different conditions.It was found that when the precursor of the prepared product was different,the product morphology and particle size were different.When the alcohol-to-water ratio of the solvent was changed,the morphology of the product changed obviously with the decrease of the amount of ethanol in the solvent.
