英文摘要	Water pollution has become serious environmental problem nowadays. Advanced oxidation processes (AOP) have been widely applied in water treatment. However, traditional Fenton reaction based on Fe2+-H2O2 system has obvious drawbacks, which limit its applications. In this study, magnetic Fe3O4 core-C shell nanoparticles (Fe3O4@C NPs) were prepared for the decoloration of methylene blue (MB) via the co-precipitation followed by the hydrothermal dehydrogenation of glucose. Fe3O4@C NPs showed high catalytic activity of the decoloration of MB through the decomposition of H2O2 in Fenton-like reactions. Fe3O4@C NPs had much higher activity than bare Fe3O4 cores, suggesting the coating of carbon enhanced the catalytic activity. The performance of Fe3O4@C NPs was better at lower pH and higher temperature, but was significantly inhibited in the presence of radical scavenger tertiary butanol. Fe3O4@C NPs could be magnetic separated and regenerated, and maintained with very good catalytic activity. The implication for the applications of Fe3O4@C NP-catalyzed Fenton-like reactions in water treatment was discussed.
