Abstract
In this study, the microwave method as a simple and fast method was used to prepare La0.7Ba0.3 MnO3 (LBMO) nanoparticles. The structural properties of LBMO nanoparticles were studied using X-ray diffraction (XRD) coupled with Rietveld refinement, Transmission Electron Microscopy (TEM) and Energy-dispersive X-ray spectroscopy (EDX). To obtain the calcination temperature, the thermogravimetric analysis (TGA) was carried out. The optical properties of samples were investigated using Ultraviolet-visible spectroscopy (UV–vis). Furthermore, the photocatalyst property of LBMO nanoparticles at different pH has been investigated. The best degradation efficiency obtained at pH-10. The Fourier-transform infrared spectroscopy (FTIR) spectrum was taken before and after photocatalytic activity, by which the perovskite structure of as-prepared samples are confirmed, and no structural change is observed.
