Energy-efficient GO-ZnO membranes were developed using a facile two-step technique. Hydrophilic GO-ZnO membranes have improved pure water permeability. GO-ZnO nanohybrid reduces membrane-solute affinity interactions. Anti-fouling GO-ZnO membranes have high trace organic rejection properties. Novel GO-ZnO membranes have the potential to compete with commercial membranes.
