MoS2 nanosheets decorated with magnetic Fe3O4 nanoparticles and their ultrafast adsorption for wastewater treatment

Magnetic Fe3O4/MoS2 nanocomposites were fabricated by a simple hydrothermal route in a water–ethanol system. The Fe3O4/MoS2 nanocomposites were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, magnetic hysteresis studies, and nitrogen adsorption–des...

More Information
Summary:Magnetic Fe3O4/MoS2 nanocomposites were fabricated by a simple hydrothermal route in a water–ethanol system. The Fe3O4/MoS2 nanocomposites were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, magnetic hysteresis studies, and nitrogen adsorption–desorption isotherms. Successful attachment of Fe3O4 nanoparticles to MoS2 sheets has been achieved. The nanocomposites which had an excellent magnetic sensitivity, could be easily and quickly separated from the suspension by applying an external magnetic field and exhibited excellent performance for water treatment. The maximum adsorption capacity for Congo red was 71mg/g. Furthermore, they presented an ultrafast adsorption for dye removal. Only about 2min was sufficient to approach the adsorption equilibrium.
