Structural Engineering of Photocatalytic ZnO-SnO2-Fe2O3 Composites

The ZnO-SnO2-Fe2O3 composites containing flower-like particles were prepared by the non-isothermal polymer-salt method. Thermochemical processes proceeding during synthesis was studied DTA/TG structure and morphology of obtained SEM XRD analysis. Prepared small amounts SnO2 Fe2O3 demonstrate high adsorption photodecomposition organic dye Rhodamine 6G in its solutions. Obtained materials show ability photogeneration chemically active singlet oxygen under visible irradiation. synergistic effect flower doping can significantly improve photocatalytic activities.
