A novel multi-functional CNT/ZnO/TiO2 nano-composite ultrafiltration (UF) membrane was successfully synthesized via hydrothermal synthesis and acid treatment with the aid of ultra-sonication. Hydrothermally synthesized TiO2 nanowires acted as the supporting matrix and the acid treated CNT/ZnO nanorods exhibited bridging characteristics to compose a cob-web like hierarchically structured nanocomposite material. This CNT/ZnO/TiO2 nanocomposite UF membrane integrated the advantages of semiconductors and carbon based nanomaterials to be endowed high mechanical strength along with high photocatalytic capability as thus leading to producing clean water at a high membrane flux with low fouling potential.
