  • 摘要: 采用溶胶-凝胶法制备了一系列钛基复合金属氧化物(FeTiOx、FeAlTiOx和CuMgAlTiOx),采用X射线衍射(XRD)、X射线光电子能谱(XPS)和透射电镜(TEM)等手段对材料的晶体结构、元素化学状态和结构形貌进行表征,以降解罗丹明B(RhB)为模型反应来评价材料的光催化性能,实验考察了光源类型、催化剂用量、光照时间等因素对RhB降解效果影响。结果表明:由于金属氧化物的协同作用,复合金属氧化物的光催化性能均优于纯二氧化钛的光催化性能,其中,以FeAlTiOx催化剂的降解效果最好,RhB的去除率高达97.5%。
    Abstract: A series of Ti-based complex metal oxides (FeTiOx, FeAlTiOx, and CuMgAlTiOx) were synthesized by sol-gel method. The physico-chemical properties of different catalysts were studied by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and transmission electron microscopy (TEM). The photocatalytic degradation performance for rhodamine B (RhB) was also investigated. Moreover, the effects of light source type, catalyst dosage, and reaction time on the degradation reaction were systematically studied. The results showed that complex metal oxides are better photocatalysts than pure TiO2. Among these complex metal oxides, FeAlTiOx has the best photocatalytic behavior, and the removal rate of RhB could reach up to 97.5%.
