Sumario:New molybdenum disulfide (MoS(2))-based core–shell nanocomposite materials were successfully prepared through the self-assembly of mussel-inspired chemistry. Characterization by Fourier transform infrared, thermogravimetric analysis, scanning electron microscope and transmission electron microscopy revealed that the surface of the flaked MoS(2) was homogeneously coated with a thin layer of polydopamine (PDA). Dye adsorption performances of the synthesized MoS(2)–PDA nanocomposites were investigated at different pH values and reaction times. Compared with pure MoS(2) nanosheets, the obtained core–shell nanocomposites showed elevated adsorption performances and high stability, indicating their potential applications in wastewater treatment and composite materials.
