Superwetting hierarchical porous silica nanofibrous membranes for oil/water microemulsion separation†
Abstract
Novel flexible, thermally stable and hierarchical porous silica nanofibrous membranes with superhydrophilicity and underwater superoleophobicity were prepared by a facile in situ synthesis method, which can effectively separate oil-in-water microemulsions solely driven by gravity, with an extremely high flux of 2237 L m−2 h−1.
