Abstract: TiO2 nanowires were synthesised directly on FTO by solvothermal method. X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM) and high-resolution transmission electron microscopy (HRTEM) were used to characterise the TiO2 nanowires. The TiO2 nanowire formation was critically affected by reaction temperature and titanium precursor. The high density and well-aligned TiO2 nanowires were formed using a mixed precursor of TiCl4 and Ti(OC4H9)4 at 180°C. The nanowires had a single-crystalline structure and grew along the <001> zone-axis rutile phase. This approach represents an advance toward a low-temperature growth of well-aligned TiO2 nanowires on transparent conducting oxide for their potential applications in dye-sensitised solar cell.
