A Liquid-Liquid Interface Process for Fabricating TiO2 Nanofiber Membrane with High Photocatalytic Activity

A membrane consisting of TiO2 nanofibers was successfully fabricated through a simple solvothermal water/n-hexane interface reaction of tetra-n-butyl titanate with NaOH followed by post treatments of acid washing and calcination. Tetra-n-butyl titanate reacts with NaOH at the interface to form high-...

More Information
Summary:A membrane consisting of TiO2 nanofibers was successfully fabricated through a simple solvothermal water/n-hexane interface reaction of tetra-n-butyl titanate with NaOH followed by post treatments of acid washing and calcination. Tetra-n-butyl titanate reacts with NaOH at the interface to form high-quality nanofibers with lateral dimensions below 200 nm and longitudinal dimensions of several tens of micrometers. The membrane is formed by the interpenetration and overlapping of the flexible nanofibers and distributed by holes with sizes ranging from several tens of nanometers to several hundreds of nanometers. Because of the porous structure, this nanofiber membrane exhibited a high efficiency in the photodecomposition of dyes in water.
