ZnFeO nanostructure was prepared as a ferrite material by using a simple sonochemistry method. The effect of different parameters such as sonication time and power were studied. By increasing sonication power and time more Fe ions reduced to Fe. This happens because H and OH radicals produced under sonication could act as a reduction agent. Therefore by increasing power and sonication time more Fe ions reduced. Pure ZnFeO nanostructure was formed when sonication time and power were 30 min and 40 W. Surface area for pure ZnFeO nanostructure was 64 m.g. Afterward, ZnFeO nanostructures were applied to treat water containing different pollutants. As-prepared nanostructures degrade 60.8, 77.9, 55.2 and 44.0% of Acid Violet 7, Acid Blue 92, Acid Red 14, and Methyl Orange under visible light during 180 min irradiation. In addition, 94.5, 84.2, and 43.0% of AV7, PhR, and Ery were degraded under UV light during 120 min irradiation. The as-synthesized ZnFeO nanostructure was characterized through the SEM, EDX, TEM, CV, DRS, BET, VSM, and XRD.
ZnFeO 纳米结构通过简单的超声化学法被制备为铁氧体材料。研究了不同参数（如超声时间和功率）的影响。通过增加超声功率和时间，可以将更多的 Fe 离子还原为 Fe。这是因为超声下产生的 H 和 OH 自由基可以充当还原剂。因此，通过增加功率和超声时间，可以还原更多的 Fe 离子。当超声时间和功率分别为 30 min 和 40 W 时，形成了纯的 ZnFeO 纳米结构。纯 ZnFeO 纳米结构的比表面积为 64 m.g。随后，ZnFeO 纳米结构被应用于处理含有不同污染物的水。在可见光照射下，制备的纳米结构在 180 分钟的照射时间内分别降解了 Acid Violet 7、Acid Blue 92、Acid Red 14 和 Methyl Orange 的 60.8%、77.9%、55.2%和 44.0%。此外，在 UV 光照射下，AV7、PhR 和 Ery 的降解率分别为 94.5%、84.2%和 43.0%。通过 SEM、EDX、TEM、CV、DRS、BET、VSM 和 XRD 对合成的 ZnFeO 纳米结构进行了表征。
