文摘
The magnetic Ni/MoS2 nanocomposites have been successfully prepared via the in situ chemical reduction method. The nanocomposites were characterized by X-ray diffraction, transmission electron microscopy, vibrating sample magnetometer, and Brunauer–Emmett–Teller surface analyzers. The experimental results clearly demonstrated the successful attachment of Ni nanoparticles to MoS2 nanosheets. The as-prepared Ni/MoS2 nanocomposites with a high surface area of 98.9772 m2 g−1 exhibited excellent wastewater treatment performance with high removal capacities toward congo red. The adsorption of CR onto Ni/MoS2 nanocomposites obeyed Freundlich isotherm model and pseudo-second-order kinetic model. Furthermore, the Ni/MoS2 nanocomposites had an excellent magnetic sensitivity and can be easily and quickly separated from suspension by applying an external magnetic field.
