Audacity! Program: Spotlight on the structuring project Nanostructured Magnets

Led by the CEA’s IRAMIS and LITEN institutes, and by the LPCNO and LGC laboratories, the Nanostructured Magnets project aims to develop a new generation of magnets, made from abundant materials with remarkable magnetic properties, for the transport and energy sectors. The work carried out could allow us to move away from the use of rare earth elements and reduce the environmental impacts associated with their production.

ICOSAHEDRA CoPd NPs FOR MAGNETICALLY INDUCED CATALYSIS

In this study, CoPd bimetallic nanoparticles (NPs) were prepared using an organometallic approach. Detailed structural analyses, including high-resolution transmission electron microscopy, X-ray diffraction, and wide-angle X-ray scattering, showed an icosahedral Pd-rich core surrounded by a less crystalline Co-rich shell. Due to their strong magnetic anisotropy, these 10 nm particles are ferromagnetic at room temperature and can act as efficient heating agents when exposed to an alternating magnetic field (AMF). The NPs were successfully tested as catalysts in hydrodeoxygenation reactions using induction heating for energy-efficient activation.

This study was published in the journal Chemistry of Materials from the American Chemical Society in February of 2025 and was selected to feature the issue’s front cover, which consisted of an artwork depicting CoPd icosahedral NPs under an AMF carrying out hydrodeoxygenation of acetophenone. The totality of the work was developed at LPCNO with Felipe Quiroga-Suavita as first author and jointly supervised by Bruno Chaudret and Lise-Marie Lacroix, from the Nanostructures et Chimie Organométallique (NCO) group.

Biomass conversion is attracting growing attention worldwide as a sustainable alternative to fossil-based resources such as petroleum and natural gas. Responding to this challenge, the NCO team has designed N-heterocyclic carbene (NHC)-stabilized, water-soluble nanoparticles of various metals and alloys to drive the selective conversion of 5-HMF, one of the most promising biomass-derived molecules. Derived from hemicellulose, 5-HMF is a versatile platform compound with high potential for transformation into valuable chemicals. This achievement has been showcased on the Inside Front Cover of the Green Chemistry journal.

At the physics-chemistry interface, Lise-Marie Lacroix works on the development of new materials by directed assembly of nanoparticles with optimized properties. By combining the study of synthetic reaction mechanisms and multi-scale physical properties, she was notably able to develop high-performance permanent magnets, without rare earth.

“This prize rewards highly talented scientists who will demonstrate how chemistry and process engineering can address current challenges facing society and provide solutions: decarbonization, recycling, advances in the fields of health and agro- food, new industrial systems… The mission of the FGL is to attract new talents, to train them in research and innovation to meet the needs of businesses and society in general,” explains Laurent Prat, president of the Gay-Lussac Federation.

“This prize, open to all chemistry disciplines, demonstrates that chemistry is at the heart of solutions to meet the challenges of today’s society. Chemists often say “Chemistry is everywhere, chemistry is life”. I completely agree with them. » summarizes Patrick Flandrin, president of the Academy of Sciences.
