- Abstract
In this research article, characterization and catalytic properties of manganese ion (Mn)-doped iron(III) oxide (Mn–Fe2O3) nanostructured particles have been reported. Mn–Fe2O3samples were synthesized via the co-precipitation - thermal decomposition (CPTD) method. Samples were analyzed by X-ray diffraction, spectroscopic, and microscopic techniques. The influence of the Mn-doping process in the phase and crystalline structure of Fe2O3was determined by powder X-ray diffractometry (p-XRD), and Fourier transform infrared (FTIR) spectroscopy. The optical energy band gap and fluorescence feature of Mn–Fe2O3samples were explored through UV–Visible absorption and fluorescence spectroscopies, respectively. The morphology and size of Mn–Fe2O3were determined through field emission scanning electron microscopy (FE-SEM). The influence of Mn3+ion concentration on the magnetic property of Fe2O3was determined. The dye pollutant removal ability of Mn–Fe2O3samples was examined by employing hydrogen peroxide (H2O2)-mediated degradation of Methylene blue (MB) and Congo red (CR) dyes under visible light conditions. The benefit of the Mn-doping process in the photocatalytic property of Fe2O3was discussed.
