Abstract

It is a worldwide challenge to efficiently separate surfactant-stabilized oil-water emulsions. The existing separation membranes are prone to fouling or are incapable of proper separation. This study is the first to realize the efficient separation of surfactant-stabilized oil-water emulsions via the delicate design and fabrication of a hierarchically nanostructured graphene-TiO2 membrane. During the oil-water separation process, this membrane demonstrates the combined advantages of high oil rejection rate and ultralow membrane fouling because of its interconnected three-dimensional nanoscale network, underwater superoleophobic interface, and self-cleaning function. Furthermore, the mechanical flexibility of this membrane endows it with great potential for wide industrial applications. This journal is
