Description
Summary:The structural, dielectric, optical, and photocatalytic properties of Manganese incorporated Bismuth Ferrite (BiFe1-xMnxO3; x = 0.00, 0.03, 0.06, 0.09 & 0.12) multiferroic nanoparticles synthesized through an easy chemical route of solvothermal technique have been investigated. The Rietveld refinement analysis of XRD data confirms rhombohedral perovskite crystal structure with insignificant existence of the secondary phase Bi2Fe4O9. The crystallite size and the particle size have been obtained from XRD and TEM. The optical band gap of prepared nanomaterials has been estimated from the study of UV–Vis spectra of pure and Mn-doped nanoparticles. The enhancement of photocatalytic degradation for methylene blue (MB) dye is observed under solar irradiation with time variation corresponds to band gap energies and particle sizes of all the nanoparticles. The photo-induced total dye degradation for the concentration x = 0.09 is about 39 % more and the dye degradation rate is 3 times higher than the pure BFO.
