Abstract Multifunctional, crumpled graphene oxide (CGO) porous nanocomposites are synthesized and assembled as reactive membranes via aerosol routes for advanced water treatments. The crumpled 3D nanostructures are highly aggregation and compression-resistant and allow for the incorporation of other, multifunctional particles inside the 3D, composite structure, such as TiO2 and Ag nanoparticles in this work. The nanocomposites not only allow high water flux via vertically tortuous nano-channels, outperforming comparable commercial ultrafiltration membranes, but also demonstrate excellent separation efficiencies for model organic and biological foulants. The 3D CGO-based nanocomposite structures have great potential as a platform material for next generation water treatment and separation technologies.
