Robust superhydrophilic and underwater superoleophobic membrane optimized by Cu doping modified metal-organic frameworks for oil-water separation and water purification

The traditional oil-water separation methods suffer from many problems such as low separation efficiency, high energy consumption, and rapid contamination by oil. We fabricated superhydrophilic and underwater superoleophobic stainless steel mesh (SSM), which was modified by copper mesh (CM) doped UiO-66-NH2, named SSM/UiO-66-NH2/CMn, for efficient oil-water separation and organic matter degradation. Our fabrication strategy mainly includes the...
