Investigation of the structural, vibrational, and magnetic properties of rare earth orthoferrite EuFeO₃ nanoparticles synthesized by the sol–gel method

A sol–gel technique was employed for generating the rare earth orthoferrite \(EuFe{O}_{3}\) $EuFe{O}_3$ nanopowder, which is of the perovskite-type. Vibrating sample magnetometer (VSM), SEM, XPS, UV–Visible absorption spectroscopy, and XRD were all utilized for examining the as-prepared particles. It comes to be that the particles are consistently structured and have an average size of 80 nm, resembling spheres. It has been discovered that the optical energy band gap of nanosized \(EuFe{O}_{3}\) $EuFe{O}_3$ is 2.1 eV. The photocatalytic activity of the \(EuFe{O}_{3}\) $EuFe{O}_3$ nonoparticles was assessed by photodegrading a number of organic dyes, including methyl orange (MO), rhodamine B (RhB), methylene blue (MB), and acid fuchsine (AF). The product displays significant photocatalytic degradation of the dyes whenever exposed to visible light. The rare earth orthoferrite EuFeO₃ has garnered significant interest for diverse applications. These include visible-light-driven photocatalysts, gas separators, and cathodes in solid oxide fuel cells, sensor materials, and magneto-optic devices.
