چکیده
This work presents the photocatalytic property of electron beam evaporated titanium dioxide (TiO2) thin films prepared at room temperature. The films were investigated for decomposition of methylene blue – eosin dye solution under visible light irradiation. The effect of annealing on structural, optical and decomposition properties was studied in detail. X-ray diffraction study revealed the amorphous nature of the film. Transmittance of the as deposited and annealed samples was good in the entire visible region. Suppressed recombination rate upon annealing enhanced the degradation of dye molecules to 32 %.
