| Résumé: | In this study, structure, microstructure, optical properties and photocatalytic degradation
of Rhodamine B (RhB) have been investigated in an aqueous heterogeneous media containing
pure and Ag doped TiO2 nanostructures thin films which were prepared by a simple
sol–gel route. Thermal analysis demonstrated that Ag content decreased the temperature
of anatase-to-rutile phase transformation. X-ray diffraction analysis confirmed that the
prepared nanostructures crystallize within anatase-type structure and that the dopant
Ag ions were not fully incorporated within TiO2 host lattice, meanwhile both the refractive
index and optical band gap were affected by Ag concentration. The photodegradation of
Rhodamine B under UV-C radiation by using pure and Ag-doped TiO2 nanostructures
showed that Ag played an important role in a significant improvement of the photodegradation
efficiency and that the optimum content of Ag ions was found to be 0.5% molar ratio |
