Preparation and Characterization of Titanium Dioxide Nanoparticles using Salvia Rosmarinus Extract

Titanium dioxide (TiO2), one of the most frequently used materials in general, has emerged as an excellent photocatalytic material for environmental applications. In this research work, we focused on the green synthesis of titanium dioxide nanoparticles using Algerian Salvia Rosmarinus extract. The leaf extract of this plant was prepared by the maceration extraction method and the synthesis of TiO2 NPs was obtained using a suitable protocol followed by calcination and activation at a temperature of 500°C. Physicochemical properties of TiO2 nanoparticles were characterized with UV Visible spectrum, attenuated total reflection infrared (ATR-IR) and zetametry analysis.  The photocatalytic activity of these synthesized nanoparticles will be tested using different pollutants.
