Résumé

This paper summarizes recent research dealing with development of titanium dioxide (TiO₂) used for environmental applications. TiO₂ plays the most important role owing to its excellent chemical and physical properties. However, the TiO₂ band edge lies in the UV region that makes them inactive under visible irradiation. In this regard, considerable efforts have been made to increase the visible light activity of TiO₂ via the modification of its electronic and optical properties. Doping TiO₂ using either anions or cations is one of the typical approaches that has been largely applied. Coupling TiO₂ with a narrow bad gap semiconductor (MxOy/TiO₂ or MxSy/TiO₂) represents another approach. This work aims to encompass the new progress of TiO₂ for an efficient application in water and wastewater treatment under visible light, emphasizes the future trends of TiO₂ in the environment, and suggests new research directions, including preparation aspects for the development of this promising material.
