Abstract

In this study, effects of precursor materials and hydrothermal reaction time on the morphology, microstructures and photocatalytic activity of TiO2 nanotubes (TNTs) were investigated. Results show that the selection of nanopowder TiO2 precursors and hydrothermal time has significantly affected the morphology, microstructure and photocatalytic property of TiO2 nanotubes. TNTs–Merck was fabricated from TiO2–Merck precursor at 130 °C for 22 h possesses a uniform structure with a range of the diameter of ~ 10 nm and length of ~ 100 nm.
