Abstract
An oil-water separation membrane is described. The oil-water separation membrane comprises a porous metal sheet with a photocatalyst layer on one side and a layer of nanoparticles and a surfactant on the other side. The layer of nanoparticles and surfactant create a superoleophobic and superhydrophilic coating that allows passage of an aqueous phase and rejection of an oil phase. The photocatalyst layer, combined with UV irradiation, enables degradation of organic contaminants in the aqueous phase. The oil-water separation membrane may be used as part of an oil-water separation system, and a filtered water product may be recycled through the membrane to increase the removal of organic contaminants.
