OFFER DESCRIPTION

This project is focusing on the rational design of asymmetric semiconductor (nano)particles having appropriate catalyst deposits on both sides. Such Janus-type objects will be able to split water into H2 and O2 under sun light, without any need of physical wiring. The project will deal with two kinds of semiconducting particles: 1) inorganic semiconductors related with the well-established know-how of ISM and 2) particles based on organic materials conventionally used in the field of organic photovoltaic devices, incorporating bulk heterojunctions, being provided thanks to the know-how of IMS.

The bifunctional particles will be produced by ISM based on the concept of bipolar electrochemistry. This approach allows depositing simultaneously at one extremity functional layers with a well-known activity with respect to hydrogen evolution, whereas at the opposite extremity it is possible to deposit via electrooxidation metal oxides or conducting polymers which allow, via their hole transporting features, the generation of oxygen. Other catalysts can also be generated via the already tested approach of indirect bipolar electrodepositon. The overall strategy has the advantage to be scalable, meaning that many particles can be synthesized simultaneously in a batch reactor. Therefore, the consortium is anticipating a new technology, able to produce solar fuels in a wireless fashion.

The work will be supervised by Prof. Alexander Kuhn (kuhn@enscbp.fr ), Prof. Thierry Toupance (thierry.toupance@u-bordeaux.fr ) and Prof. Guillaume Wantz (guillaume.wantz@enscbp.fr ). Their respective groups are equipped with top-level instrumentation for the elaboration and characterization of nanostructured materials, their modification by electrochemical techniques and the related photochemical testing.

Offer Requirements

Skills/Qualifications

The Post-doc will elaborate bifunctional semiconductor particles, characterize their physico- chemical properties and test them in terms of water-splitting efficiency. A strong background in materials science, electrochemistry and/or photochemistry is required. Knowledge in catalysis would be a plus.

Application maximum 3 years after completion of the PhD
