Heterogeneous catalysis of Fenton‐like process provides new alternatives to overcome the drawbacks of traditional Fe 2+ ‐H 2 O 2 system. Herein, the modification of Fe 3 O 4 with SiO 2 /C in one‐pot hydrothermal reaction to prepare Fe 3 O 4 /SiO 2 /C nanoparticles (FSCNP) for the Fenton‐like catalysis in neutral environment is reported. FSCNP could catalyse the decomposition of H 2 O 2 at various pH values to decolourise methylene blue (MB), in particular the neutral pH 7.5. Correspondingly, the chemical oxygen demanding of MB solution was significantly removed. FSCNP‐H 2 O 2 system was resistant to radical scavengers. Higher H 2 O 2 concentration and temperature would accelerate the decolouration of MB in FSCNP‐H 2 O 2 system. The implications to the future applications of FSCNP in dye decolouration and water treatment are discussed.
