In this study, highly pure rutileTiO(2) nanorods (NRs) structures were grown on fluorine-doped tin oxide (FTO) coated glass substrates by using a one-step hydrothermal method. The effect of the growth time on the structure and surface properties of the obtained products has been studied. The X-ray diffraction analysis and the Raman spectroscopy indicated that the films were single-crystalline rutile phase. At lower hydrothermal time, TiO2 NRs singly distributed with small diameter are found showing a high contact angle with ethylene glycol. When the hydrothermal reaction increases, nanoflowers (NFs) with a large diameter are formed over the TiO2 NRs leading to superhydrophilic surfaces. These nanostructured thin films can be tailored to the requirements of specific applications involving water and ethylene glycol. Copyright (C) 2021 Elsevier Ltd. All rights reserved.
