Job description

Offer DescriptionCall for expression of interest descriptionThe is a highly prestigious renowned EU-funded scheme. It offers talented scientists a unique chance to set up 2-year research and training projects with the support of a supervising team. Besides providing an attractive grant, it represents a major opportunity to boost the career of promising researchers.Research laboratories in Brittany are thus looking for excellent postdoctoral researchers with an international profile to write a persuasive proposal to apply for a Marie S. Curie Postdoctoral Fellowship grant in 2024 (deadline of the EU call set on 11 September 2024). The topic and research team presented below have been identified in this regard.Main Research FieldChemistry (CHE)Research sub-field(s)Physical-Chemistry, Renewable Energies, Spectroscopy, CatalysisKeywordsUltrafast spectroscopy, (photo)electrocatalysis, optical control of solidsResearch project descriptionThe transition to a sustainable future requires developing new technologies capable of exploiting renewable sources. In particular, the electrification of fossil- fuel based processes in industry and transport requires new materials that can store and transduce electrical energy.Electrocatalytic and (photo)electrocatalytic materials offer a great opportunity to generate renewable fuels and chemicals for industry. For example, key reactions include the splitting of water to produced H2 or the reduction of CO2 into C-based compounds. However, enhancing the efficiency and selectivity of (photo)electrochemical reactions remains a big challenge.One of the key problems stems from the difficulty of characterising the catalytic interface of heterogenous systems under working conditions. This prevents us from elucidating the reaction mechanisms and limits our ability to control reactivity in a similar way to what can be achieved with homogeneous molecular catalysis. A particular challenge of solids is that they are prone to form defects during catalysis. However, how defects and lattice distortions impact the steps of the catalytic cycle remains unknown.This project has to main objectives (1) explore the role that defects and imperfection play in controlling the efficiency and selectivity of photo/electrochemical reactions and (2) developing new strategies that use tailored light pulses to modulate reactions and tune the reaction mechanisms on demand.The project will build on the experimental expertise and research interests of the candidate and the facilities that are already available within our group. The research will involve the implementation of optical control tools based on multi-pulse laser experiments and their integration with analytical characterisation methods. In addition, experiments at large-scale facilities, such as synchrotrons or XFELs, will likely be required to establish how disorder influences catalytic mechanism through the modulation of the electronic and atomic structure of the catalysts or fluid phase.Relevant literature includes: (i) ; (2) ; (3) , (4) (6)Supervisor(s)Ernest Pastor is a CNRS Junior Professor Chair at IPR-The Institute of Physics of Rennes in France. He did a PhD in Photochemistry at Imperial College London and worked as a researcher in Spain (fellow at ICFO and INAM) and in the UK and USA (postdoc at Imperial College and the Berkeley National Lab). Ernest uses ultrafast lasers, x-ray radiation and electrochemistry to study functional solids, such as catalytic oxides or phase-change materials. He is interested in using laser pulses to manipulate defects and structural imperfections. In 2022 Ernest was awarded an ERC Starting Grant to explore how light can be used to control polarons and point defects in solids for energy conversion and storage applications.Relevant publications * Johnson A.S. et al All-optical seeding of a light induced phase transition with correlated disorder.Nature Physics.
