Synthesis of La2CoFe2O7 Nanocomposite and its Photocatalytic Application to Remove Organic Dyes

Wastewater from textile factories is one of the most important sources of environmental pollution, so it is necessary to treat these wastewater. Therefore, the decomposition of colors using photocatalysts, which is one of the advanced oxidation processes, has been studied. The present work introduces the synthesis of the magnetic mixed metal oxide La2</sub>CoFe2</sub>O7</sub> (LCoFO) nanocomposite as an effective photocatalyst by co-precipitation method. The synthesized metal oxide was characterized by infrared spectroscopy (FT-IR), X-ray diffraction pattern (XRD) and transmission electron microscopy (TEM). The alternating force gradient magnetometer (AGFM) shows the magnetic behavior of the LCoFO nanocomposite. In this research, the photocatalytic properties of LCoFO nanocomposites using photolysis of methyl violet (MV), malachite green oxalate (MG), and eriochrome black T (EBT) were investigated under ultraviolet light irradiation in different parameters such as temperature, solution pH, dye concentration, catalyst amount, and UV radiation time. The results showed that these nanocomposites have good photocatalytic performance.
