Abstract Magnetic Feⁿ⁺@GO (MFGO) nanocomposite was prepared by coprecipitation and applied as a heterogeneous Fenton catalyst for catalytic oxidation of methyl blue (MB). The scanning electron microscopy (SEM), High-Resolution transmission electron microscopy (HRTEM) and X-ray photoelectron spectroscopy (XPS) indicated that the GO nanosheets were successfully loaded by catalytically active particles (i.e., Feⁿ⁺, iron oxide). The effects of pH value, initial H₂O₂ concentration and catalyst dosage on the degradation efficiency were investigated. The degradation efficiencies for the system of H₂O₂, MFGO and H₂O₂ with MFGO after 120min reached 7.83%, 25.58% and 99.19%, respectively. The degradation efficiency of MB was 99.90% at the optimal operating conditions of 0.79mol/L H₂O₂ and 0.75g/L MFGO, pH=8. With the pH ranging from 3to 11, the degradation efficiency of MB was still higher than 99%. Even MFGO was reused for six consecutive runs, the degradation efficiency of MB still reached 95.08%. Furthermore, the novel catalyst was preferable to be utilized in wide pH value and took the advantages in magnetic separation and reuse.
