【Abstract】 In this work, cerium oxide（CeO₂） nanoparticles were synthesized by a hydrothermal method. CeO₂-MnFe₂O₄, synthesized via depositing MnFe₂O₄ nanoparticles onto CeO₂, was utilized for organic contaminant degradation. Rhodamine B（RhB） and Methylene blue（MB） were used as the model emerging organic contaminant to test the Fenton-like activity of CeO₂-MnFe₂O₄,respectively. CeO₂-MnFe₂O₄ could degradation more than 95% of the model emerging organic contaminant in 90 minutes. In addition, the composite catalysts exhibited good magnetic recovery performance and reuse performance, which proved the potential of CeO₂-MnFe₂O₄ in water treatment.更多还原
