The L’Oréal Foundation has awarded the L’Oréal-Unesco “For Women in Science” fellowship to Céline Pagis, a PhD researcher at IFP Energies nouvelles/IRCELYON. From 1,000 applicants, and with 29 other PhD and post-doctoral researchers.

Céline Pagis was singled out by the L’Oréal Foundation for the quality of her work as well as her passionate commitment to her profession and her desire to share her research.

Congratulations to this young generation of female researchers who will contribute to future scientific progress!

Every year in France, the L’Oréal Foundation, in partnership with the French Academy of Sciences and Unesco, awards fellowships to 30 female PhD and post-doctoral researchers, to support their promising research activities.

Applied to the field of the chemistry of materials and catalysisCéline Pagis’ thesis is sponsored by IFPEN and supervised by IRCELYON (the Lyon Institute of Catalysis and Environmental Research), a CNRS-Université Claude Bernard Lyon 1 joint research unit. The aim is to synthesize a new zeolite crystal morphology, in the form of “nanoboxes”[1-5], with two associated advantages:

  • thin walls enabling the accelerated diffusion of molecules within the zeolite crystals during catalytic reactions[6, 7];
  • a large internal cavity, making it possible to increase the molecule storage capacity.




The potential of these new materials was jointly tested at IRCELYON for an application concerning the storage of a molecule that inhibits the ripening of some fruits and vegetables. Given that more than one third of all fruit and vegetables is wasted between field and plate, this application could represent a lever for reducing food waste

Experimental tests, conducted at IFPEN on the HTE platform, also concerned an application in the field of hydrocracking with a view to gaining an understanding of the diffusion phenomena at play in these new zeolite crystals[7].

It should be recalled that zeolites are materials that are widely used in industry for a variety of applications (oil industry, adsorption and separation, gas purification, etc.) since their beehive structure of cavities and channels means chemical substances can be trapped in their pores and molecular transformations accelerated.

Céline Pagis is currently a heterogeneous catalysis researcher at IFPEN.
