Magnetically separable CoFe₂O₄/ZnO and CoFe₂O₄/ZnO/Ag nanocomposites were successfully synthesized using CoFe₂O₄ nanoparticle as core by a simple precipitate route. The structural, morphology and functionality of prepared samples were analyzed using X-ray diffraction, field emission scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, diffuse reflectance spectroscopy, and vibration sample magnetometer. The micro-structural study approved that the synthesized nanoparticles have spherical morphologies with average particle size between 30 and 47 nm. The influence of nanocomposites on the acid violet and acid brown degradation was investigated under ultraviolet light. The CoFe₂O₄/ZnO nanocomposite showed enhanced photocatalytic activity, achieving acid violet and acid brown degradation efficiency of 76% and 63% respectively, rather than other samples. The increase in photocatalytic activity of CoFe₂O₄/ZnO hybrid may be associated with the formation of a suitable internal structure between CoFe₂O₄ and ZnO. Magnetic measurement indicated that CoFe₂O₄/ZnO is ferromagnetic with the magnetization saturation value of 25 emu/g, which is suitable for magnetic recovery by using an external magnetic field.

利用CoFe ₂ O ₄成功合成了磁可分离的CoFe ₂ O ₄ / ZnO和CoFe ₂ O ₄ / ZnO / Ag纳米复合材料纳米颗粒为核心，通过简单的沉淀途径。使用X射线衍射，场发射扫描电子显微镜，透射电子显微镜，傅立叶变换红外光谱，漫反射光谱和振动样品磁力计分析了所制备样品的结构，形态和功能。微观结构研究证实，合成的纳米颗粒具有球形形态，平均粒径在30到47 nm之间。在紫外光下研究了纳米复合材料对酸性紫和酸性棕降解的影响。CoFe ₂ O ₄/ ZnO纳米复合材料具有增强的光催化活性，与其他样品相比，酸性紫和酸性棕的降解效率分别为76％和63％。CoFe ₂ O ₄ / ZnO杂化物的光催化活性的增加可能与在CoFe ₂ O ₄和ZnO之间形成合适的内部结构有关。磁性测量表明，CoFe ₂ O ₄ / ZnO是铁磁性的，磁化饱和度值为25 emu / g，适合通过外部磁场进行磁回收。
