Offer Description
LEPMI is a laboratory specialized in electrochemistry, whose topics are essentially centered on environmental sciences and green energies http://lepmi.grenoble-inp.fr/ . The research will be undergone in the team of electrocatalysis. The post-doctorate will take part in the joint laboratory between LEPMI and Michelin. Job description : Nanostructured Pt-group-metal-based carbon-supported catalysts (the usual hydrogen oxidation/evolution catalysts) degrade very fast and deeply in alkaline media, which compromises the AEMFC/AEMWE durability. The degradation mechanisms remain poorly understood, which prevents one to propose relevant mitigation strategies to counter these degradations. In addition, the fate of non-noble catalysts in this environment is not clear and requires further work to be unveiled.
. Pt and Pd-based catalysts will be studied at first (commercial references), and then home-made catalysts based on Ni. The potential window of the AST will be adapted to the targeted conditions (-0.2 0.5 V vs. RHE for hydrogen reactions, and 0.6 1.0 V vs. RHE or 1.0 1.6 V vs. RHE for oxygen reactions) ; the effects of the temperature (25 and 60°C) the gas atmosphere (Ar, H2 and O2) will also be evaluated. The way the active surface area and the activity for the target reaction do evolve will be measured in rotating disk electrode (RDE) or gas diffusion electrode (GDE). These electrochemical markers will be compared to the physicochemical and textural properties of the materials, determined from TEM, XRD, and ICP-MS. The use of in situ coupled techniques (FTIRS, DEMS, ICP-MS), and advanced microscopies (STEM-HAADF-XEDS, identical location TEM: ILTEM), will help unveiling the degradation mechanisms at stake and their dependence to the operating conditions.

Skills/Qualifications
Proficiency in English and French is required. In addition, international experience will be a decisive asset. PhD diploma, with a profile of materials sciences, chemical engineering or electrochemistry. Specifics of the position Knowledge in electrochemistry/electrocatalysis, and materials characterization (in particular transmission electron microscopy) techniques are mandatory.
The candidate shall justify his proficiency in TEM operation. Curiosity and autonomy are two essential qualities to fulfill this study. The candidate shall be capable to work in the joint laboratory between LEPMI and Michelin.
