Submitted Abstract

Today the most studied and used photocatalyst is titania or TiO2. However, its solar efficiency remains strongly limited by its electronic, surface and chemical characteristics. This project aims to provide clues to produce photocatalysts by design, capable to adapt to different reactions. These alternative systems will be conceived using ferroelectric oxides, with a strategic objective on understanding the role played by the electronic and photocatalytic properties of nano-objects and hybrid architectures based on them. Beyond their intrinsic polar distortion useful for photocatalysis, ferroelectric oxides offer a wide variety of electronic and chemical properties making them materials of choice as future photocatalysts. However, few knowledge on these perovskite oxides for this particular application has been yet achieved. By first unveiling the mechanisms of the charge carrier photoexcitation in nanoferroelectrics, new photocatalytic architectures with tuneable properties will be designed and realized. The final goal of the present international mobility project is to establish the first basic principles of ferroelectrics nanostructures as water nano-cleaners, chemically stable and environmentally friendly, with expanded reactivity ranges.This FOXCAT project aims at sharing complementary and cross knowledge and know how’s to in fine identify and formulate future technology concepts dedicated to high performance photocatalytic systems.The acknowledged expertise of Dr. Ingrid C. Infante from the SPMS laboratory UMR8580 CNRS-Ecole Centrale Paris-Supelec (ECP-Supelec), in nanoferroelectrics will fully contribute to the achievement and success of the FOXCAT project that will be performed within the nanomaterials research unit at the Materials Research and Technology (MRT) Department of the Luxembourg Institute of Research and Technology (LIST).Moreover, being at the frontier between two distinctive research lines of the LIST-MRT leaded respectively by Dr. Lenoble and Pr. Kreisel, the present FOXCAT project proposed by Dr. Infante will serve as a bridge between both groups at the LIST in addition to the international link to the SPMS laboratory UMR CNRS-ECP-Supelec, being such a collaborative initiative fully supported by the LIST.
