Missions

The PHOENIX project upgrades CO2 and waste plastic to value-added products using a combination of electrochemical (EC) and photoelectrochemical (PEC) technology, thereby supporting the frameworks of EU Green deal and REPower EU initiatives and sustainable practices across the globe. It is envisaged that the technology will be validated by building a demonstrator with the best integration of EC, PEC, and their catalyst technologies. Additionally, the initiative actively reduces carbon-based emissions, promotes economic growth, and noticeably raises the technology readiness level (TRL) of existing CO2 utilization methods and plastic recycling technologies to TRL 3-4, denoting notable advances in technological maturation. The project PHOENIX seeks to facilitate the step-wise conversion of CO2 into chemical fuel such as propanol and simultaneously transform PET plastic waste into value-added products such as glycolic acid through an innovative strategy utilizing solar energy. The proposed strategy stems from designing a multi-reactor CO2 reduction pathway that smoothly integrates photovoltaic electrolyzer (PV-EC) and photoelectrochemical (PEC) technologies.

Activités

The postdoctoral researcher will be involved in

(i) the synthesis and development of electrocatalysts for the conversion of CO into n-propanol (Cu-Pd, Cu-Ru, Cu-Ag…) and
(ii) the optimization of electrode architecture for stable and efficient n-propanol production (with a target of 50% faradaic efficiency towards this product).

Importantly, the PHOENIX project is geared towards the efficient integration of solar energy conversion and electrocatalytic systems, rather than the discovery of novel materials, and this philosophy will be reflected in the objectives of the postdoctoral researcher. An emphasis in the optimization of device architecture and integration is therefore present in the project. The developed cathodes will ultimately be powered by solar energy through their combination with a photoanode and an external (but fully integrated) semi-transparent perovskite solar cell provided by the partners of the project.

The postdoctoral researcher will thus be involved in the characterization of material and device performance from the electrocatalyst to a lab-scale solar-powered photoelectrochemical device. Importantly, the photoanode and its associated electrocatalyst will be developed independently by partners of the consortium. In addition, the postdoctoral researcher will be involved (i) in the dissemination and reporting activities linked to his work within the PHOENIX project and (ii) in the coordination and organization of the electrocatalytic CO2 and CO reduction activities in our research lab (experimental coaching of PhD students and interns on specific techniques – within reason, experimental setup development and maintenance, knowledge and ability to discuss recent scientific literature on the topic, etc.).

Compétences

A PhD in chemistry or chemical engineering is preferred. A strong background in electrochemistry is required, with experience in electrochemical device assembly and operation. Experience with flow electrolyzers and/or zero-gap membrane-electrode assemblies is considered as an important skill (but not formally required). Experience with standard (nano)material characterization techniques and analytical techniques for product characterization is a plus. Candidates able and willing to work independently, demonstrate initiative in their research work, and develop their leadership abilities are encouraged to apply. In return, we are committed to provide as much financial, material and theoretical scientific support as the project resources allow to the postdoctoral researcher, including (but not limited to) publication of his work in high-profile peer-reviewed scientific journals.
