Titania nanotubes have attracted considerable attention due to the high specific surface area, excellent photocatalytic activity and ion-exchangeable ability. Synthetic methods of titania nanotubes have been extensively investigated, which include assisted-template method, sol-gel synthesis, electrochemical oxidation and hydrothermal method. However, these conventional methods have some limitations such as complex multistep procedures, toxic solvents, long duration of reaction and high energy consumption. In this study, a green and efficient microwave-assisted flow synthesis method was developed. The as-synthesized titania nanotubes were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD) and micro-Raman. The effects of microwave irradiation temperature, pressure, and residence time on the physicochemical properties of titania nanotubes were investigated.
