Description of the thesis topic
The transformation of biomass into the platform molecules encompasses a high degree of complexity since biomass is rich in polyols, carbonic acids, aldehydes, and ketones. As these functional groups are very reactive, the control of the selectivity of the reaction is critical. The design and implementation of catalytic materials for biorefineries is key to the development of a competitive self-sustainable bio-based economy. The project aims to provide new concept of photocatalytic materials able to provide in high efficiency and selectivity added-value products to support the world bioeconomy.
The PhD goal is a design and production of various nanocomposite able to control the light−matter interaction and convert the incident light efficiently into organic value-added products. Briefly, core-shell nanostructure providing a strong metal-support interaction with metallic nanoparticles in the sub-nanometer scale, and the student will adjust the relative position of the two constituents in the nanocomposite and compare the performance in photocatalysis. The material synthesis strategy is a combination of soft chemistry and colloidal chemistry in order to obtain tunable photocatalyst morphology. On the technical side, materials will be essentially characterized by: UV-vis spectroscopy, GC-MS, HPLC, Transient photocurrent, time resolved microwave conductivity, transient absorption spectroscopy, scanning electron microscopy, transmission electron microscopy, and photocatalytic test.
The Institute of Physical Chemistry, Orsay /University of Paris Saclay is looking for a PhD candidate with skills in materials chemistry, soft chemistry synthesis, physical chemistry, photoelectrochemistry and biomass valorization. To reinforce our team, we are looking for a highly motivated candidate with a solid experience in materials synthesis, physico-chemical characterization by time-resolved spectroscopy, electrochemistry, photoelectrochemistry and photophysical studies. The project will be conducted within the framework of a project funded by the National Research Agency.
