Missions

The SyMMES lab at CEA Grenoble is offering a post-doc position to a young qualified and highly motivated candidate to develop novel materials with Pb-free perovskite nanocrystals encapsulated in the pores of mesoporous silica for CO2 photoreduction.

Activités

The postdoc will work under superirvision Dmitry Aldakov (CNRS researcher), coordinator of a French collaborative project. The overall goal of the project is to produce valuable solar fuels using as light absorbers less-toxic halogenated perovskites encapsulated in various nanoporous matrices. Several parameters will be tested: pore sizes, types of nanoporous matrices, chemistry of the perovskites to enhance their stability and control their size. The obtained perovskite nanocrystals grown in the pores will be studied by a variety of methods to identify their chemical composition, structure, and stability. Several treatments (surface passivation, doping etc.) will be performed to further improve the optical properties of the nanocomposites and establish structure-properties relationships. The most promising optimized nanomaterials will be used for the efficient photocatalytic CO2 reduction into solar fuels in collaboration with an academic partner.

Compétences

A candidate must hold a recent internationally-recognized PhD-equivalent degree in Materials Science, Chemistry, or Physics.
Candidates should have demonstrated experience and hands-on expertise in the chemical synthesis and characterization of halogenated perovskites and/or colloidal quantum dots (nanocrystals). Knowledge of XRD and microscopy techniques as well as some skills in Schlenk line and/or glovebox synthesis will be an advantage.

Contexte de travail

The SyMMES laboratory is a joint CEA, CNRS, UGA research unit. It brings together multi-disciplinary skills (physics, chemistry, biochemistry, biology) for fundamental and proof-of-concept research into the challenges of new energy technologies, health technologies and information technologies. These multidisciplinary skills are also applied to research in the fields of nanotoxicology, radiobiology and metal toxicology. The post-doc will be based in the Synthesis, Structure and Properties of Functional Materials (STEP) team. He will work under the supervision of Dmitry Aldakov (CNRS researcher), coordinator of this French ANR project in collaboration with 3 different laboratories.
