Highly Photocatalytic Active and Easily Recycled Sulfur-Doped TiO2 Nanotubes

Abstract

Abstract: Sulfur-doped TiO2 nanotubes (STNTs) were prepared by the two-step hydrothermal method. It has the single-crystalline anatase TiO2 with outer diameter of 10–20 nm and length of approximately 200 nm. The pseudo-first-order reaction rate constant k of STNTs is about 5 times higher under UV-light and 10 times higher under sunlight irradiation than those of undoped TiO2 nanotubes.

Key words: two-step hydrothermal method, sulfur doping, titania nanotube, photocatalytic activity, sedimentation
