Abstract

Strong corrosive emulsion sewage must be properly treated because it is not only very harmful to the environment, but also an enormous waste of chemical resources. Here we fabricated a pine-branch-like TiO₂ nanofibrous membrane via an electrospinning and hydrothermal process. Besides neutral emulsions, the obtained membrane could separate various highly corrosive acidic (pH < 0), basic (pH > 14), and salty oil-in-water emulsions with efficiencies higher than 99% without extra force assistance, which is highly promising for aquatic environment protection as well as resource recycling.
