In a few words

After a PhD in heterogeneous catalysis (Paris 6 Univ., 2003-2006), during which I acquired skills in mineral synthesis, spectroscopies, catalytic testing and computational modelling, I chose to explore more deeply the potential of ab initio calculations for the modelling of catalytic surfaces relevant to industrial applications. I thus joined IFP Energies nouvelles, with the mission of implementing ab initio calculations within experimental research programs. Since then, I have expanded my activity at the interface between quantum chemistry and experimental catalysis. The impact of my research was recognized by my nomination in 2014, as the project leader of the EYRING research program, then in 2019 of the FERMI research program, gathering specialists in various disciplines, with the aim of building kinetic models (for refining, petrochemistry, biomass conversion and pollution abatement) from ab initio calculations. The originality and relevance of my research has also been recognized in the scientific community as shown by the indicators below:

- 104 articles published in peer-reviewed journals, 1 book chapter, and 5 patents

- H=38, 4593 citations, (source: Web Of Science, May 14, 2024)

- more than 40 invited talks at (inter)national conferences, summer-schools, seminars (including keynotes at EUROPACAT 2019 and FEZA 2021). 12 oral presentations given at (inter)national conferences & workshops (+ ~80 more as co-author).

- 4 Young Scientist Awards (Edith Flanigen 2015, Physical Chemistry Division of SCF 2016, Catalysis Division of SCF 2018, Groupe Français des Zéolithes 2023).

I also served as president of the Groupe d’Etudes en Catalyse (GECat, 2014-2017), and I have been / am involved in the organization of several international conferences. In particular:



Industrial heterogeneous catalysts are complicated systems. In the context of the energetic transition we are currently facing, understanding their structure at the atomic scale, and their precise role in the catalytic elementary steps is crucial for the conception of ever more efficient catalytic systems. My research works are devoted to the understanding and prediction at the atomic scale, of the structure and reactivity of realistic heterogeneous catalysts of industrial relevance, for applications in the fields of energy and chemistry. To achieve this goal, Density Functional Theory (DFT) calculations are performed, in strong connection with experimental studies (spectroscopies, reaction kinetics) and kinetic modelling. The structure and behaviour of surface sites of complex systems have thus been predicted, accounting for the influence of the chemical environment (temperature, partial pressures of reactants or of other compounds present in the reaction atmosphere), to as to assign spectroscopic (IR, NMR, XANES, …) feature, and to quantify the kinetic feature of the elementary steps for various catalytic cycles. Finally, thermokinetic data calculated ab initio have been introduced in kinetic models to as to predict macroscopic data (such as TOFs, selectivity) by multi-scale kinetic modelling. This approach, when validated by cautious kinetic experiments, is a powerful way for both the unravelling of the reaction mechanism, and for the construction of robust kinetic models based on chemical atomistic investigations rather than on analytical fitting. These achievements pave the way for the experimental optimization of several kinds of catalytic systems in the field of the synthesis of clean fuels and chemicals, from fossil and renewable sources, and also in the field of pollution abatement.

In particular, I have unravelled the structure and behaviour of Brønsted acid sites at the surface of amorphous silica-alumina (ASA), a very important catalyst and support in refining and acido-basic catalysis in general, thanks to ab initio calculations [12]. The structure of these sites were debated for decade. We called these sites "Pseudo-Bridging Silanols". The structure of these sites recently appeared to be compatible with a set of DNP NMR feature [49], and exhibit very specific behaviour with respect to basic probe molecules [18,25,27,28,43]. Our calculations were able to explain and anticipate their reactivity with respect to carbenium ions [46], and to quantify the difference between ASA and alumina with respect to the interaction of the surface with metallic cations [47]. A fully original behaviour of the Pseudo-Bridging Silanols for the dehydration of isopropanol into propene (an important reaction in the context of biomass conversion and green chemistry) was also revealed, by the combination of DFT calculations, experimental kinetic measurements, and ab initio-based multi-scale kinetic modelling [56]. Pseudo-Bridging Silanols are indeed the only one being able to combine Lewis and Brønsted moieties, required to optimally stabilize the HO- leaving group. From a methodological point of view, this study demonstrates the feasibility and the high-potential of the construction of kinetic models from mechanisms and rate constants calculated ab initio.


We have also established original models for the external surface of MOFs[17,20] and zeolites (beta, H-ZSM-5)[61, 77], providing key explanation for their reactivity. In particular, at the external surface of zeolites, mild Bronsted acid sites (BAS) and Lewis acid sites were revealed by DFT at the outermost surface, whereas the pore mouth still contains strong BAS. Still with the aim of going closer and closer to reality, the mechanisms at the origin of the formation of EFAl species in zeolites were investigated and the regioselectivity of their formation unraveled for several zeolite frameworks [45,52]. 

external surface MFI

I also contributed to the atomic-scale elucidation of the dynamical behaviour of sub-nanometric platinum particles supported on alumina, depending on structural and environment parameters (size [13,78], support [19,31], composition[30,72,73], temperature, H2[23,44,70], O2[67,70], hydrocarbon pressures[40,68]), demonstrating a huge impact of the cluster ductility, even in the course of a catalytic cycle [68].


All these studies, corroborated by spectroscopic (XANES) and experimental catalytic measurements, challenge the concept of structure sensitivity/insensitivity of catalytic reactions. Similar methodologies were also applied successfully for the quantification of the sulfation of NOx traps [32,39,41], of the environment of copper in chabazite for NH3-SCR [64,66], and of the reactivity of gamma-alumina for isopropanol dehydration [48,51,54].

My current works follow the direction given by these first successes in the implementation of the multi-scale kinetic approach, addressing ever more realistic cases, such as the isomerization of ethylcyclohexene in EUO zeolite frameworks.[63,69] The location of the active sites was identified by the calculations, and confirmed experimentally by the comparison of the performance of the EU-1 and ZSM-50 (same framework but different location of sites) zeolites. We also aim at obtaining ever more accurate rate constants, for example by performing advanced ab initio molecular dynamics calculations [71,75,81]. In general, the proposal of ever more realistic models is aimed at [79, perspective review]. Finally, building more and more realistic models for complex catalytic systems is a strong motivation, in particular in the context of the ROAD4CAT project and the CARMEN common laboratory.
