Optical Properties and Chemical Stability of WO3 and TiO2 Thin Films Photocatalysts

Abstract. The aim of the paper is to explain the correlations between the optical properties of WO3 and TiO2 films and the chemical stability in different environments required for a future utilisation as catalysts in wastewater treatment and in building a photoelectrochemical cell (PECC). The crystallinity was investigated using X-Ray Diffraction and the electrical properties were determined by current – voltage analysis. The optical properties of the films were the subject of UV – VIS analysis.

Keywords: photoactivity, WO3, TiO2.
