(186n) Fast and Green Microwave-Assisted Synthesis of Titania Nanotubes

Microwave-assisted synthesis possesses exclusive benefits of uniform, rapid, and volumetric heating and is able to significantly reduce reaction duration. Many researches have been done in microwave crystalline of titania nanotubes, however, most of them are batch synthesis which are limited to small-scale batch preparation. In this study, a fast and green microwave-assisted flow synthesis method for continuous production of titania nanotubes is developed. The synthesized materials were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD) and micro-Raman. The effects of different parameters, including microwave irradiation temperature, pressure, and residence time on the physicochemical properties of titania nanotubes were investigated.
