Flower-like SnS2 decorated with MgFe2O4 nanoparticles and reduced graphene oxide (rGO) nanosheets were successfully synthesized by a facile solvothermal method. The morphological and crystal structure results confirmed that MgFe2O4 nanospheres were uniformly anchored on the surface of SnS2 flower-like structure with the decoration of rGO nanosheets. The UV-vis diffuse reflectance spectra indicated that the SnS2-MgFe2O4/rGO photocatalyst had a strong visible light absorption. The sample exhibited the highest photocatalytic activity for the degradation of methylene blue under visible light irradiation. The mechanism of improved photocatalytic activity was finally proposed.
