Novel Nano-Scale Surficial Film on Titania

The project team intends to perform a systematic investigation of the formation and stabilization of surficial complexions of silicon oxide on titania as a function of various thermodynamic variables such as temperature, chemical potential etc. The current generation of silica-titania materials does not have a thermodynamically stable core-shell type structure. In contrast, this research would focus on understanding the formation and thermodynamic stability of the silicon oxide based complexions in titania. Although the scope of this project is limited to silicon oxide-titania, we envision that the results will have major impact on the understanding on the photocatalytic properties of titania.
