Sn-Doped Hematite Nanoparticles for Potential Photocatalytic Dye Degradation. In IOP Conference Series: Materials Science and Engineering (Vol. 739, No. 1, p. 012042). IOP Publishing.https://doi.org/10.1088/1757-899X/739/1/012042http://nur.nu.edu.kz/handle/123456789/4629Recently, low-cost hematite (α-Fe2O3) metal oxide semiconductor has attracted enormous attention for the photoelectrochemical water splitting and photocatalytic applications. The main purpose of this work is to study the effects of Sn-doping on the photocatalytic properties of hematite nanoparticles (NPs). Morphology and physicochemical properties of prepared samples were analyzed using X-ray diffraction analysis (XRD), transmission electron microscope (TEM), and UV-vis spectroscopy. Rhodamine B (RB) dye was used as a model organic pollutant to test the photocatalytic activity of prepared samples. It was found that the photocatalytic activity of Sn-doped hematite NPs was higher than that of the undoped hematite NPs. The recyclability tests suggested that 3 mol% Sn-doped hematite NPs can be used as a promising reusable photocatalyst for dyes degradation.enAttribution-NonCommercial-ShareAlike 3.0 United StatesResearch Subject Categories::NATURAL SCIENCES::ChemistryArticle
