Abstract
TiO2 porous thin films were prepared using polystyrene (PS) latex particles as template in conjunction with dip coating technique. In this work, the resulting films were produced by the infiltration of the TiO2 sol particles into the voids between the templates (templating technique). X-ray diffraction spectra (XRD) indicated that the porous TiO2/PS thin film was anatase structure. High quality of porous structures was observed by Atomic Force Microscopy (AFM) images. The transmittance spectrum has shown that elaborated thin films present a high transparency in the visible range. The photodegradation of methylene blue (MB) in the presence of Tio(2)/PS thin films was performed. We found that the fabricated films exhibited better photocatalytic activity than the pure TiO2 thin films under illumination. As a result, the porous TiO2/PS thin film would have great potential in photocatalytic devices.
