초록 | TiO2 nanotubes are made by treating TiO2 powder with NaOH followed by hydrothermal treatment. The shape and structure of the TiO2 nanotubes are determined by the precursor, number of moles of NaOH, temperature, reaction time, and washing process. In this research, TiO2 nanotubes that crystallize at low temperatures were synthesized and their structural characteristics were examined. After a TiO2 sol was made via the sol-gel method, it was subjected to hydrothermal conditions to increase the specific surface area and obtain high purity TiO2 by regulating the particle size and shape of the nanotubes. H2Ti3O7 appeared at 180 °C. The structure of the nanotubes was affected by the hydrothermal reaction temperature. The TiO2 particles turned into TiO2 nanotubes due to the condensation polymerization of OH- and H+, which were weakly bound. The NaOH concentration of 10M was the most effective for the synthesis of TiO2 nanotubes. |
