Description of the thesis topic
Structured molecular catalyst layered hydroxide materials for selective CO2 electroreduction reaction
Keywords: CO2, Hybrid materials, organometallic – layered hydroxydes - Electrocatalysts
Description A PhD position is available at the Département de Chimie Moléculaire (DCM) for 36 months, starting from September 2020.
The project is part of the funded CALHYCO2 research ANR project, a collaborative research consortium (2020-2024) between three laboratories (DCM Grenoble, IPCMS Strasbourg and ICCF Clermont-Ferrand). The CALHYCO2 general theme is to develop innovative effective and selective catalysts for the electrochemical transformation of CO2 into chemicals that can be used for organic synthesis (e.g. CO) or into energy products (e.g. HCOOH, an H2 vector).
Significance and objectives: The development of an efficient, economically, and ecologically viable process for the CO2 ElectroReduction Reaction (CO2ERR) would make the CO2 recovery possible, by using it as a raw material for the synthesis of various products and would open up new perspectives for CO2 conversion, a challenge to be taken up in order to propose a solution to major environmental and energy-related challenges. To facilitate the CO2RR, make it selective and avoid the competing proton reduction reaction, it is necessary to develop catalysts.
The PhD research project concerns more specifically the design and the development of innovative nanostructured layered hydroxide (LOH) catalysts containing metal-organic complexes, for selective CO2 electroreduction. LOH metal-based functional host matrices (CO2 adsorbent and proton source) have been selected to structure, to modify and control the catalyst local environment. Due to their sophisticated structure, the developed hybrid catalysts should considerably improve the efficiency and durability of the catalytic CO2 electroreduction. Mechanistic studies, to decipher the factors governing the redox catalytic activity of these materials, will complete the experimental developments.
The PhD student will focus his (her) work at DCM, on two complementary approaches in strong interaction with IPCMS and ICCF. One concerns the development of innovative complexes (molecular catalysts) the other is to address the issue in selectivity, in particular regarding formate vs. competing H2 evolution reaction (HER) in the CO2ERR.
Profil: The candidate should hold a M.Sc. degree or equivalent in chemistry with a strong interest for organometallic synthesis, molecular electrochemistry, electrochemical mechanistic studies, and electrocatalysis. Complete application in a single pdf file (detailed CV, one-page cover letter, one page summary of Master thesis, University marks, and contact information from previous supervisors) should be sent before the 31 March of 2020.
