摘要

本研究描述了一种简单、清洁的声化学合成Fe/ZnO空心球纳米结构作为高效紫外-可见光催化剂的方法。利用x射线衍射(XRD)、傅里叶变换红外光谱(FT-IR)和场发射扫描电镜(Fe - sem)对制备的Fe/ZnO空心球纳米结构进行了表征。然后，在紫外和可见光(λ > 420 nm)照射下，评价了催化剂在水溶液中降解亚甲蓝和刚果红的光催化活性。此外，为了说明形貌对这些有机染料降解的影响，合成了具有木状、花状、棒状和纳米颗粒形态的Fe/ZnO纳米结构，并测定了它们的光催化效率。结果表明，Fe/ZnO空心球具有较强的光催化活性，可作为去除水中染料污染物的极具潜力的光催化材料。

Facile Synthesis of Fe/ZnO Hollow Spheres Nanostructures by Green Approach for the Photodegradation and Removal of Organic Dye Contaminants in Water

In this research, a facile and clean sonochemical synthesis was described for Fe/ZnO hollow spheres nanostructures as high-efficiency UV-Vis light photocatalyst through an environmentally-friendly procedure. X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), and field-emission scanning electron microscopy (FE-SEM) were utilized for the investigation of the produced Fe/ZnO hollow spheres nanostructures. Then, the photocatalytic activities of the catalysts were evaluated on the degradation of Methylene Blue and Congo Red in an aqueous solution under both UV and visible light irradiation (λ > 420 nm). Also, to illustrate the influence of morphologies on the degradation of these organic dyes, the Fe/ZnO nanostructures with the wood-like, flower-like, rod-like, and nanoparticle morphologies were synthesized and the photocatalyst efficiency of them was determined. The obtained results confirmed that the Fe/ZnO hollow spheres have significant photocatalytic activity compared to other morphologies and could be used as outstanding potential photocatalyst materials for removing dye pollutants from water.
