摘要：

Pure and Zn doped manganese (II, III) oxide (Mn3O4) nanoparticles were prepared by simple chemical precipitation method at room temperature with different atomic percentages (6, 12, 18) of Zn. The obtained products were subjected to various characterizations namely powder X-ray diffraction (XRD), microstructure and morphology were investigated by scanning and transmission electron microscopy (SEM and TEM), element analysis was done by energy-dispersive X-ray spectroscopy (EDX). Specific surface area of all the samples were measured by Brunauer-Emmett-Teller (BET) analysis. The optical absorption (UV-vis) property of the samples, confirmed electronic transitions and increase in the band gap of the products. The as-synthesized samples were used for degrading methylene blue (MB) dye of which 12at% Zn in Mn3O4 showed best oxidation efficiency compared to other samples.
