Photocatalytic Degradation of Malachite Green Dye via An Inner Transition Metal Oxide-Based Nanostructure Fabricated through a Hydrothermal Route

This experimentation focuses on an inner transition metal oxide-based nanostructure LaFeO3 which was fabricated by a hydrothermal route for photocatalytic degradation of dye under visible light irradiation. The fabricated nanostructure was characterized by various techniques, including X-ray diffraction (XRD), which depicts the crystalline nature and size of the synthesize nanostructure which is 45 nm; Field emission scanning electron microscopy (FE-SEM), which determined the overall morphology of the nanocomposite; and energy dispersive X-ray (EDAX) analysis, which established the presence of La, O, and Fe in the sample. The photocatalytic activity of the samples was checked for the decolorization of malachite green (MG) dye. It was observed that the nanostructure showed maximum response with more than 80% degradation of MG in 80 min.
