| description | For environmental remediation, it is significant to design membranes with good mechanical properties and excellent photocatalytic activity. In this work, RGO/TiO<sub>2</sub> membranes with heterogeneous structures and good photocatalytic efficiency were synthesized using the method of electrospinning combined with a thermal treatment process. In the binary nanocomposites, RGO was tightly adhered to TiO<sub>2</sub> fibers and by simply adjusting the loading of RGO, the strength and modulus of the fibrous membranes were improved. Notably, the RGO-permeated TiO<sub>2</sub> fibers exhibited 1.41 MPa in tensile strength and 140.02 MPa in Young’s modulus, which were 705% and 343% of the original TiO<sub>2</sub> fibers, respectively. Benefiting from the enhanced light response and the homogeneous and compact heterogeneous structure, the synthesized RGO/TiO<sub>2</sub> membranes displayed good antibacterial performance with a photocatalytic inactivation rate of 6 log against <i>E. coli</i> within 60 min. This study offers a highly efficient alternative to inactivate <i>E. coli</i> for the synthesis of TiO<sub>2</sub>-based membranes. |
