Nanomaterials to provide better catalytic performance in the Laboratory of Surface Organometallic Chemistry (C2P2 / LCOMS)

Obtaining simple high value added chemical products by valorization of the biomass should constitute a sizeable advance at both an economic and environmental level. In particular, the metathesis reaction of functional olefins and more precisely those between ethylene and w-unsaturated esters present in large quantities in vegetal or animal fat allows key intermediates to be obtained for the synthesis of lubricants, surfactants, fragrances, prostaglandins, and polymers, etc. This catalytic reaction has the advantage of being extremely selective, not very costly in energy and does not lead to the formation of non-valorizable products.

Our project is the conception and preparation of solid nanomaterials capable of catalyzing this reaction. Until now, various well-defined catalysts containing catalytic sites which are unique in terms of chemical structure and reactivity (of the Ru-N-heterocyclic type) have been obtained and they show an important catalytic performance in the envisaged reaction. Moreover, they have a high stability and recyclability and are easily separable from the reaction products.
