Flower-like and micro-rods rutile Titanium Oxide (TiO2) were fabricated on Fluorine-doped Tin Oxide (FTO) glass substrate by hydrothermal synthesis. TiO2 was prepared with different volumes of Titanium(IV) butoxide (TBOT). The hydrothermal reaction time and temperature were optimized. The amount of TBOT were varied to be 2, 4, 6, 8, and 10 mL to achieve the property of micro-sized hydrophobicity on its surface. The samples were characterized by using Field Emission Scanning Electron Microscopy (FE-SEM), water contact angle measurement (WCA) and X-Ray Diffraction (XRD). Results from FE-SEM showed the micro-rods and flower-like TiO2 grown on the FTO substrate. The WCA results of the sample with 8 mL of TBOT revealed an increase in contact angle. It has been proven from XRD data analysis that rutile crystalline micro-rods and flower-like structures were successfully grown on the surface of FTO with the peaks on TiO2 of the sample. © 2021 National Institute of Optoelectronics.
