Abstract

In this work, we have fabricated rutile- phase TiO₂ film on a fluorine doped tin oxide (FTO) substrate by a facile hydrothermal method and studied for methylene blue (MB) dye decolourization under direct noon sunlight irradiation. The prepared film was characterized by UV–visible spectroscopy, X-ray diffraction (XRD), Fourier Transform Infrared (FT-IR), Raman spectroscopy and Field Emission Scanning Electron Microscopy (FESEM). XRD analysis confirms that the hydrothermal treatment facilitated the crystallization of the rutile TiO₂ phase on FTO plate. The functional group, surface morphology and structural property were analyzed from FTIR and FESEM respectively. The optical band-gap was evaluated to be 3.2 eV from the UV–visible spectroscopy. The photocatalytic activity of rutile-TiO₂ film was evaluated which showed 78 % Methylene blue dye decolourization in 240 min.
