The research in our group deals with the reproducible preparation of transition metal nanoparticles of controlled size and their applications in polyphasic catalysis. Metal nanocatalysts, generally defined as particles between 1 and 10 nm in size, are obtained by the bottom-up approach and one of the crucial parameters during their preparation to obtain reproducible properties remains their stabilization.
The originality of our chemistry relies on the synthesis in water of colloidal suspensions which could directly be used in biphasic liquid-liquid systems or to deposit nanoparticles on inorganic, magnetic or mesoporous supports. The catalyst recycling is particularly studied.
Metallic nanoparticles in solution
During the last years, our laboratory has gained an expertise in the preparation and the stabilization of aqueous suspensions of metallic nanoparticles by quaternary ammonium surfactants, modified cyclodextrins or nitrogen ligands. These colloidal suspensions have proved to be active catalysts for various catalytic reactions: arenes hydrogenation (Rh, Ir, Ru), the tandem dehalogenation/hydrogenation reaction (Rh, Pd), the carbon-carbon coupling reaction (Pd) or the asymmetric hydrogenation of activated ketones (Pt).
Deposit of metallic nanoparticles on support
We have also developed a clean and easy methodology based on simple impregnation to deposit metallic nanospecies on inorganic supports (SiO2, TiO2). Two methodologies could be applied: the wet or dry (fluidized bed) impregnations. These materials have proved to be very active for arene hydrogenation and their application to the degradation of organic pollutants from aqueous effluents is under current investigation.
Moreover, we have prepared nanoparticles on mesoporous supports by a surfactant-assisted method and the materials are active catalysts for arene hydrogenation.

Alain Roucoux was born in Valenciennes (North of France) in 1963. He received his Ph.D. degree from the University of Lille in 1992 under the supervision of Professor A. Mortreux in the field of the asymmetric hydrogenation catalysis. In 1993, he joined the teaching staff of the Ecole Nationale Supérieure de Chimie de Rennes (ENSCR) before becoming Assistant-Professor (Maître de Conférences) in 1994. In 2001, he received his Habilitation and was promoted Professor in 2003. Since 1997, he develops the synthesis of noble metal nanoparticles in water for polyphasic catalysis. He manages the Nanocatalysis group of the Organometallics: Materials & Catalysis Team (UMR CNRS 6226) – He is the author of 100 international scientific publications (h=32 with one paper in Chem. Rev. 2002 > 1500 times quoted), 5 book chapters and 9 patents. (update Scopus 06/2018)
Audrey Denicourt-Nowicki obtained her PhD degree from the University of Lille under the guidance of Dr F. Agbossou-Niedercorn and Pr A. Mortreux (2003). After working as a post-doctoral fellow with Pr C. Moody at the University of Exeter (United Kingdom), she joined the Ecole Nationale Supérieure de Chimie de Rennes (UMR CNRS 6226, Institut des Sciences Chimiques de Rennes) as a senior lecturer in 2004. Her research interests include the synthesis of metal nanoparticles, either in solution or on support, for applications in polyphasic catalysis. She is author of 56 publications, 5 book chapters and one patent. (update 10/2016)
