In this project we propose to investigate a new class of photocatalysts based on colloidal quantum dots that are expected to be i/ efficient with visible light and iii/ able to photocatalyze redox reactions in smooth conditions, as shown by a recent study in our laboratory.

The PhD project will consist in two mains parts. First, some well-known quantum dots systems (CdS, CdSe, ZnSe, ...) will be investigated as redox photocatalysts for new radicalar reactions recently developped for fine organic synthesis.

Second the PhD student will developp and new controlled size connection’s of quantum dots with silver nanoparticles by a click chemistry approach (Huisgen cycloaddition of azides and alkynes). Such assemblies quantum dots/ silver nanoparticles will promote the electron/hole separation by electron transfer from the quantum dots to the silver nanoparticles and should enable us to improve the efficiency of quantum dots based photocatalytic systems.
