Degradation of Methylene Blue Dye Using ZnO/NiFe2O4 Photocatalyst Under Visible Light

The effective synthesis of ZnO/NiFe2O4 photocatalyst with a co-precipitation technique was used to degrade dyes in the air in this study. XRD, SEM-EDS, and other equipment are used to characterize the crystalline phase, surface morphology, and chemical composition of photocatalysts. The exact peaks of the nanocomposite XRD pattern corresponded to cubic spinel NiFe2O4 and hexagonal wurtzite ZnO, according to the results. At a NiFe2O4 to ZnO molar ratio of 2:0.1, all nanocomposites demonstrated photocatalytic activity in decomposing methylene blue dye 50 ppm higher than pure ZnO. After 40 minutes of exposure to visible light, the product demonstrated photocatalytic activity, with a degradation efficiency of 92 percent.
