Master 2 : Synthesis of free noble metal catalysts for the hydrodeoxygenation reaction of lignin derivatives

Topic : Biomass valorisation is an important topic to mitigate climate change. Biofuels and green chemicals can be produced from lignocellulosic biomass such as wood. Lignin is the second most abundant macromolecule on earth (after cellulose). Thus, the lignin refining could produce aromatic compounds which are important building blocks currently obtained from crude oil. But, according to literature, the challenge remains in the develop of stable and selective catalysts to desoxygenate lignin. The goal of the M2 project, is to pursue the development of low cost, not toxic and selective catalysts free of noble metals such as iron, copper, nickel and cobalt. Here, metal supported catalysts will be synthesized from metallo-surfactant templating. This route, investigated in our laboratory, affords to prepare porous silica catalysts with well dispersed nanometric metallic clusters in the silica walls. Moreover, the combination of two different metallo-surfactants for the synthesis of the silica porous catalyst will be studied to aim the enhancement of the catalytic activity in the deoxygenation reaction (heterogeneous catalysis). After synthesis, the catalysts will be characterized in terms of texture, morphology, and metals content.

Master 2 Internship: Synthesis of exotic boronic ester using organomagnesiates complexes.

Context: Organomagnesiates are bimetallic complexes that result in combining a “polar” (e.g. an organolithium) with a “soft” organometallic (e.g. organomagnesium), which behaviour is significantly different from those of the precursor. The principle is a synergy created by mixing two different organometallic reagents allowing increased selectivity and reactivity. Indeed, those reagents tolerate easier a bromine or ester function for example. They can as well be used under non-cryogenic conditions compared to the monometallic reagent. Moreover, those heterobimetallic reagents are from cheap and abundant metals which are the key towards the development of sustainable chemical processes. Combined with a chiral ligand, they also can be very powerful to induce enantioselectivity. In the last few years, we developed and studied (chirales) organomagnesiates complexes as metal-halogen agent for the synthesis of diversely (chirales) 3-substitued and 3,3’-disubstitued (aza)phthalides.


Research objectives: The aim of this project is to use organobimetallic complexes’ properties to develop an original straightforward way to access to (chiral) alkyl and (hetero)aromatic boronic ester using a specific key boron reagent, iPrBHCl.

PhD: Viral Protease-assisted Combined Antiviral Therapy with photoactive “Lock and Release” supramolecular-antiviral-dots

Context of the PhD research

Human coronaviruses (HCoV) are enveloped RNA viruses associated with mild to severe respiratory infections in humans, such as colds and pneumonia. To date, there are no specific approved treatments for these HCoV infections. Thus, the development of anti-HCoV agents therefore remains a public health emergency. The objective of the VIPRO-COMBAT project is to synthesize photoactive supramolecular antiviral dots (SAD) assemblies, unique as an "intelligent" prodrug delivery system, allowing site-specific activation by the viral protease, thanks to attaching a peptide sequence to a virus inhibitor, such as an antimicrobial peptide. A “Lock and Release” system will ensure the controlled activation of the prodrugs, which are then activated by near-infrared light radiation at the level of the infected tissues. This will guarantee a functional and controlled multimodal antiviral approach, combining the advantages of optical and acoustic imaging based on the study of vibrations induced in matter by light. Another objective of the study will be to elucidate the interaction of SAD with the target cell by transcriptomic analysis, but also the impact of the treatment on the immune response and on the phenomena of inflammation. The project is therefore a proof of concept for the use of anti-infective prodrugs activated by a viral protease, associated with a fluorescence bio-imaging system and phototherapy.

Profile of the candidate

We look for a candidate holding (or near completion of) a Master’s degree in Organic Chemistry, Pharmacy or similar, with competitive marks, eligible to apply for PhD fellowships. A background in organic synthesis, medicinal chemistry and/or chemical biology is highly recommended.

The PhD student will evolve in an environment composed of closely collaborating partner labs, such as CRAN (UL), RCSI (Dublin, Ireland) and LRGP (UL), with an international team composed of chemists, physicians, biologists, medical staff and pharmacists.

PhD position: Noble metals-free heterogeneous catalysts for lignin deoxygenation into aromatics

The PhD project will aim at synthesizing heterogeneous catalysts based on abundant metals, whose key parameters will be optimized: (i) textural properties of the supports, and in particular the stabilization of a hierarchical porosity, (ii) oxophilicity / acidity of the surface, (iii) and fine characteristics of the metals (dispersion, localization and composition). Thus, silica supports with hierarchical porosities will be synthesized, modified by the introduction of different oxide phases (ZrOx, TiOx, AlOx, ZnO), and then the metal phases (Ni, Fe, Co and Cu) will be dispersed in a controlled manner on the surface of the pores to obtain single atome to clustered supported catalysts. These catalysts will be studied for the HDO of model oxygenated molecules (m-cresol, anisole and guaiacol) under moderate hydrogen pressures (2-4 MPa) before being tested on real lignin in a reaction micropilot (IC2MP partner). The properties of the catalysts (activity, aromatic yield, and stability) will be rationalized by DFT studies conducted on the adsorption of model oxygenated molecules, taking into account the effect of H2O, CO and CO2 inhibitors (LPCT partner). All these results will allow the description of the reaction pathway and the obtaining of key kinetic data in real conditions of reaction conducted over lignin (at LRGP partner).
