Underwater superoleophobic carbon nanotubes/core–shell polystyrene@Au nanoparticles composite membrane for flow-through catalytic decomposition and oil/water separation

Abstract

A hierarchical composite membrane, consisting of an underwater superoleophobic carbon nanotube film and core–shell polystyrene@Au nanoparticle-assembled membrane, is fabricated to achieve simultaneous flow-through degradation of water-miscible toxic organic molecules and effective separation of oil/water emulsion. This multifunctional composite membrane allows continuous treatment of polluted oily wastewater, making it a promising candidate for water purification.
