Synthesis of La0.6 Sr0.4MnO3 nanoparticles using microwave irradiation and investigation of its photocatalytic activity

Abstract

In this paper nanoparticles, La0.6Sr0.4MnO3 via microwave radiation method is provided. The structural, magnetic, optical and photocatalyst properties by X-ray diffraction (XRD), Transmission electron microscope(TEM), Fourier transform infrared spectroscopy (FTIR), Vibrational sample magnetometer (VSM) and UV–Vis spectroscopy (UV-Vis) were studied. Lattice constants, cell volume, and space group as well as length and angle of bonds obtained by XRD analysis. Using the UV-Visible spectrometer, an examination of the particle absorption spectrum confirmed the existence of a band gap like semiconductors at about 1.8 eV. The degradation of nanoparticles on methyl orange dye under visible light evaluated about 83% in 50 minutes.
