BiOI/Brookite TiO2复合材料光催化降解四环素的研究
|
Abstract:
以板钛矿TiO2为研究对象，采用水热法将BiOI对其进行复合制备了BiOI/brookite复合材料。利用X射线衍射(XRD)、扫描电子显微镜(FESEM)对复合材料进行了表征，对样品的晶相组成及形貌进行了分析讨论。以四环素(TC)为目标降解物，考察了BiOI/brookite复合材料的光催化活性。结果表明，在可见光照射下，110 min内8 mol% BiOI/brookite复合材料对TC的降解率高达82%。
The research focused on brookite TiO2, and BiOI/brookite composite materials were prepared by combining BiOI with it using a hydrothermal method. X-ray diffraction (XRD) and field emission scanning electron microscope (FESEM) were used to characterize the composites, and the crystal phase composition and morphology of the sample were analyzed and discussed. Using tetracycline as the target pollutant, the photocatalytic activity of BiOI/brookite composites was investigated. The results indicated that under visible light irradiation, the 8 mol% BiOI/brookite composites achieved a degradation rate of 82% for tetracycline within 110 min.
