The world is now facing a water scarcity crisis due to waste, pollution, and uneven distribution of freshwater resources, which are limited. Thus, the creation of innovative, economical, and effective methods for purifying water is crucial. Here, the photo-assisted degradation of methylene blue (MB) dye under visible light and UV was achieved by using RGO photocatalyst loaded with ZnCuFeO in three different loaded 10%, 20%, and 30% called MRGO 10, MRGO 20, and MRGO 30. Furthermore, all prepared samples was characterized by X-ray diffraction (XRD), fourier transformation infrared (FTIR), transmission electron microscope (TEM), vibrating sample magnetometer (VSM) and Raman analysis. After 40 min, the high photocatalytic efficacy effectively eliminated about 95.2% of the 10 ppm MB using 20 mg of MRGO 20 NPs at pH9 Visible light. From the results, the photocatalytic activity of MRGO 20 reduced to 54.6% after five cycles of methylene blue (MB) dye degradation. The produced samples' observed efficacy in both UV and visible light may encourage continued research into more effective photocatalysts for the filtration of water.
由于水资源的浪费、污染以及淡水资源分布不均（淡水资源有限），当今世界正面临水资源短缺危机。因此，创造创新、经济且有效的水净化方法至关重要。在此，通过使用负载有ZnCuFeO的RGO光催化剂（分别以10%、20%和30%的三种不同负载量，即MRGO 10、MRGO 20和MRGO 30）实现了亚甲基蓝（MB）染料在可见光和紫外光下的光辅助降解。此外，所有制备的样品通过X射线衍射（XRD）、傅里叶变换红外光谱（FTIR）、透射电子显微镜（TEM）、振动样品磁强计（VSM）和拉曼分析进行了表征。40分钟后，在pH9可见光条件下，使用20毫克MRGO 20纳米颗粒，高光催化效率有效去除了10 ppm亚甲基蓝中的约95.2%。结果表明，经过五个循环的亚甲基蓝（MB）染料降解后，MRGO 20的光催化活性降至54.6%。所制备样品在紫外光和可见光下观察到的效果可能会促使人们继续研究更有效的用于水过滤的光催化剂。
