Multifunctional 3D polydimethylsiloxane modified MoS2@biomass-derived carbon composite for oil/water separation and organic dye adsorption/photocatalysis

Oily wastewater causes serious pollution to the environment and has aroused widespread concern. Hereby, a novel, sustainable and hydrophobic 3D polydimethylsiloxane modified MoS 2 @biomass-derived carbon composite (PMC) was fabricated by simple hydrothermal carbonization , self-assembly, freeze-drying, and hydrophobic modification methods based on natural renewable resources. With a water contact angle of 147.2°, the PMC exhibits excellent hydrophobic and oleophilic properties and further processes high adsorption capacity for various organic solvents and oils, and the maximum volume adsorption capacity reached up to 98.5% (v v −1 ). Moreover, the PMC can maintain a high oil-absorption capacity even after 10 cycles, showing good recoverability and reusability. In addition, the as-prepared PMC also can be applied in the removal of water-soluble organic pollutant . Benefiting from its facile fabrication and excellent properties, the developed PMC can be a promising candidate for broad environmental applications.
