Description
Summary:The ZnO-SnO[sub.2]-Fe[sub.2]O[sub.3] composites containing flower-like particles were prepared by the non-isothermal polymer-salt method. Thermochemical processes proceeding during composites synthesis was studied by DTA/TG method. The structure and morphology of obtained composites were studied by the SEM and XRD analysis. Prepared composites containing small amounts of SnO[sub.2] and Fe[sub.2]O[sub.3] demonstrate the high adsorption and photodecomposition of the organic dye Rhodamine 6G in its solutions. Obtained materials show the ability of the photogeneration of the chemically active singlet oxygen under the visible irradiation. The synergistic effect of the flower structure and Fe[sub.2]O[sub.3] doping can significantly improve the photocatalytic and adsorption activities.
