Summary: In this study, hedgehog-like micro/nanostructure nickel particles were successfully fabricated via a hydrothermal route and modified with octadecyltrichlorosilane (ODTS) to exhibit superhydrophobic/superoleophilic properties, making them suitable for oil/water separation. The dense narrow thorns of the nickel particles contribute to their high sorption capacity for various organic solvents and oils, and they also demonstrate good resistance. Moreover, the modified particles can be used for oil/water emulsion separation with high efficiency.

Summary: The discharge of oily sewage and frequent oil spills have caused serious harm to human production, life, and the ecological environment. The presence of surfactants in water makes oil-water mixtures form oil-in-water emulsions which are difficult to separate using traditional methods. The oily wastewater containing water-soluble pollutants like dyes and heavy metal ions also poses great harm to human health and the environment. A cost-efficient and environmentally friendly underwater superoleophobic pine nut shell membrane (PNSM) was prepared, which allows the separation of oil-in-water emulsion and adsorption of dyes and heavy metal ions. The PNSM also showed excellent toughness and flexibility, making it a promising candidate for multifunctional oily water remediation.
