O2 and CO2 as sustainable energy sources: to boost the performances of hybrid nanomaterials by coupling electrocatalysis and plasmonics

The activation of O2 and CO2 through electrochemical reduction (ORR and CO2RR) is highly promising for developing sustainable and alternative energy conversion technologies. The electrochemical reduction of these abundant feedstock requires strong electrocatalysts in terms of i) efficiency, ii) selectivity and iii) durability.
We have recently demonstrated that metallic nanoparticles (Au, Ag, Pt) functionalized wit a covalently-bound monolayer of molecular cavities exhibit better performances toward ORR and MOR as nanocatalysts, with, notably, better selectivity and durability. The immobilized organic ligands allow a tuning of the interfacial reactivity which has positive impact on the selectivity of the reaction while increasing the stability of the catalysts under operation (Adv. Mat. Interf. 2020 DOI 10.1002/admi.202001557,ChemElectroChem, 2020, DOI 10.1002/celc.202000132).
The goals of this PhD project will be to even enhance the efficiency and selectivity of the target reactions, namely comcerning the CO2RR reaction which is highly challengin nowadays. In addition to a specific design of the organic cavities inspired from metalloenzymes for the development of nanohybrid catalysts, we will also take benefit from the properties of the nanoparticles (Ag, Au, Cu) by coupling electrocatalysis with plasmonics. We will then evaluate the synergy of such an approach through a plasmon-mediated electrocatalysis (Adv. Mat. 2020, doi.org/10.1002/adma.202000086).
The research work will be run at Institut des Sciences Chimiques de Rennes in the framework of a collaborative project funded by the french national research agency (project MARCEL, ANR 2021). The nanomaterials will be synthesized and characterized in the host laboratory by employing a combination of available techniques (IR, Raman, XPS spectroscopies, SEM, TEM, ATG, etc). The electrochemical performances will be evaluated by using the state-of-the-art techniques (RDE, RRDE) and electrochemical microscopy (SECM). Complementary techniques such as gas chromatography will help in the products identification. All facilities are available in the host laboratory.

Required skills
The recruited PhD will be in charge of the preparation, characterization of the hybrid nanoparticles and of the evaluation of their electrochemical performances toward ORR and CO2RR. The recruited PhD will analyze the data and will monitor bibliographic literature.
The applicant should complete or hold a Master’s degree. The candidate should be enthusiastic and has interest in at least one of the following fields: electrochemistry, physical chemistry of surfaces, synthesis and characterization of nano-objects.

Funding : 36-months contract from CNRS (french scientific research organism) with gross monthly salary of 2135 € (netto 1715 €).

Interested applicants are invited to send a CV and a letter of motivation before June, 15, 2022.

Applications are invited for the position of Postdoctoral research associate in the field of Plasmonic contributions to N2 and CO2 co-electrolysis.

This position is part of a project aimed at gaining a fundamental electrochemical insight supporting the rational catalyst design plasmonic contributions to N2 and CO2 co-electrolysis.

The major challenges in electrochemical ammonia synthesis are related to the low activity and selectivity of currently available electrocatalysts for N2 reduction. Therefore, significant improvements to cell materials, including electrocatalysts and electrolytes, would be needed to achieve those targets. Therefore, this is an encouraging aspect for addressing the challenge related to the urea synthesis via CO2 and N2 co-electrolysis.

Applications are invited for the position of Postdoctoral research associate in the field of batteries & supercaps.

This position is part of a project aimed at gaining a fundamental electrochemical insight of redox materials for electrochemical energy storage

The advent of nanotechnology enabled new electrode materials that flexibilization the limits between Electrochemical Capacitors and batteries. Whether it is a dual-layer electrochemical capacitor, be it a hybrid electrochemical capacitor, the use of nanostructured materials allowed these devices to achieve energy performance close to that of batteries.
In the present study, using electrochemical techniques, we will try to explore these limits between capacitors and batteries and to understand the origins of the electrochemical capacitance and behavior of the electrodes that make up the device. In this way, we will produce electrodes with good physical and electrochemical qualities and study their performance in ionic liquids that have been developed in the group with large electrochemical window and good transport property. Research will be carried out at the Institute of Chemistry of the University of São Paulo (IQ-USP), Brazil.
The need for high-power lithium-ion batteries and energy density leads to a safety-related problem due to problems related to the use of organic solvents typically used as electrolytes. It is known that ionic liquids (LIs) can be used as electrolytes because they are not flammable and have high thermal and electrochemical stability, however, it is necessary to have LIs with good transport properties that allow the easy diffusion of lithium.
=This opportunity is open to candidates of any nationality. The selected candidate will receive a Post-Doctoral fellowship from the São Paulo Research Foundation (FAPESP) in the amount of R$ 7,373.10 monthly and a research contingency fund, equivalent to 10% of the annual value of the fellowship which should be spent in items directly related to the research activity.

PhD topic on “Nanostructured electrode architecture for high efficiency Fuel Cells”
PhD position in in the group of Professor Philippe Vereecken at imec and the University of Leuven (KU-Leuven), Leuven, Belgium. (4-year period to be filled in asap).


Website: https://www.imec-int.com/en/energy-technologies/power-to-molecules-p2m

State-of-the-art hydrogen Fuel-cell technology relies on carbon-based membrane electrode assemblies with catalyst coatings for the oxygen reduction reaction (ORR) and hydrogen oxidation reaction (HOR). Recently, our group has established a fabrication process for a three-dimensional metal nanomesh by combining anodization and electrodeposition processes. Unique to this nanomesh is its very large internal surface area of around 30x per micron in mesh thickness combined with a very high porosity of 70-80 % allowing easy transport of gasses through the regular spaced nanocages. Furthermore, the fully interconnected metal nanowire array has low resistance as compared to the carbon current collectors reducing Ohmic drop. In this PhD topic, a membrane electrode assembly or MEA based on this nanomesh will be designed for increasing efficiency of the fuel cell. A few micrometers thin electrodes already provide an effective catalytic surface area exceeding 100x while having excellent accessibility of reagents and products. The compact MEA leads to Fuel cells with high energy density while having low catalyst loading. A systematic investigation of transport and the confinement of reaction products in the nanomesh will provide the necessary insights for further optimization of the nanomesh architecture for maximum performance. Also, the catalytic properties of the nanomesh itself will be investigated, e.g., next to having a catalytic nanomesh material, 2D thin-film coatings will behave intrinsically different than nanoparticle decorated current collectors. The catalytic nanomesh is believed to be more durable than nanoparticle decorated current collectors. Finally, ionic coupling and ion transport within the nanomesh architectures will be addressed. This radical new design in electrocatalytic electrodes is expected to boost performance of gas diffusion electrodes for fuel cells and other vapor based electrochemical devices.

 

This PhD position is part of the BE-HyFE project, a training network with 16 PhD researchers working on hydrogen technology at Belgian universities and research institutes. The design, development, manufacturing, and electrochemical characterization of the materials will be performed at imec. This specific project will be in collaboration with the University of Liège where PEM-FC test benches will be used to characterize complete MEAs. Several trainings and workshops will be organized each year for the PhD students and their advisors within the training network.
