A novel synthetic route of metal/graphene nanocomposites has been designed on the basis of non covalent interactions. Applicable to various elements, this approach has led to new materials with remarkable properties in soft oxidation catalysis in particular. In the final phase of the project, we wish to develop applications of these nanomaterials for electrochemical devices of energy conversion and storage. The role of the Engineer will be to develop such applications.
The chemical engineer will be asked to:
- perform chemical syntheses of nanomaterials
- characterize these nanomaterials with a ensemble de physico-chemical techniques enabling determination of texture, structuration, surface chemistry, thermal stability, redox properties, size and interaction between nanoparts within the composites
- evaluate their electrocatalytic properties, especially in ORR and OER
- evaluate their properties towards storage of an electrical charge.
- present the results to the project team on a regular basis (every month)
- plan the experiments aimed at optimizing chemical and structural formulations and characteristics of the nanomaterials on the basis of the feedback of the team.
Optimisation of the performances will hence be carried out in a rationnal manner, on the basis of structure-function relationships by the whole team in which the chemical engineer will have a key role.
Secondary tasks will include:
- managing chemicals involved in the manipulations (storage and usage according to best practice, ordering, parcel reception and checking,handing over delivery sheet according to administrative rules...)
- managing the equipment dedicated to the Engineer manipulations (use according to best practice, maintenance, servicing...)
- training as a user on plateform equipment (XRD, BET, FTIR, TGA...)
- managing analysis requests on external equipements (TEM, ICP,...) or equipment managed by a single authorized user (SEM, XPS, TPR/TPO/TPD,...): filling the submission form, determination and communication of analysis conditions, sample preparation or conditioning, discussion with the authorized user,...)
• Recent Master/Engineering diploma (obtained in or after 2017) in physical chemistry/chemical engineering with a specialisation in electrocatalysis.
• Strong knowledge in electrochemistry (energy storage, supercapacitors), electrocatalysis (OER, ORR), and physico-chemical (XRD, BET, TGA, FTIR, Raman, XPS, TEM) and electrochemical (CV, RDDE) characterisation of nanocomposite powders, associated with a first practical experience (few month-internship) in electrochemistry applied to energy conversion.
• Operational know-how: bottom-up synthesis of carbon-based nanocomposite powders, electrode preparation
• Fluency in English, both spoken and written. Fluency in French is a plus.
• Ability to produce, put into shape, analyze, present and potentially interpret results, on the basis of the state of the art
• Ability to find scientific information and data in the specialized literature
• Ability to write reports
• High autonomy, initiative, multi-task, organisational skills, efficient time management
• Ability to work as part of a team, skills in collaborative work on multidisciplinary projects, reporting and communication skills
• Ability to work in compliance with safety rules and procedures, ability to work on deadlines, adaptability, flexibility
• Ability to learn, openness to skills development
The Engineer will be part of the "Photocatalysis and photoconversion" (dir. V. Keller) and "Electrochemistry and Energy Conversion" (dir. E. Savinova) teams of the Institut of Chemistry and Processes for Environment, Energy and Health (ICPEES). Their research is focused on the design of nanomaterials for Energy and Environnement applications, more specifically applications related to novel renewable fuels, such as sun and hydrogen. The research is based on the understanding of the molecular mechanisms involved. He (she) will work under the supervision of Drs. V. Caps, S. Pronkin et G. Kéranguéven in the frame of ANR OH Risque 2014 project PICATA, which is related to the « Development of ultra-stable hydrophobic heterogeneous catalysts using pi interactions. ».
PICATA is one of the 15 basic research projects with high scientific potential funded by the National Research Agency (ANR) in 2014, all fields included.
The successful candidate will benefit from access to the whole park of instrumentation available at the institute and in the close surroundings, the know-how of experts in the fields of nanomaterials, electrocatalysis and energy storage, the scientific life of the institute and the particularly rich scientific and cultural microcosm of the University of Strasbourg (Université d'Excellence).
