Description of the group

The SRCO team broadly aims at the design and reactivity of novel organometallic complexes for small molecules activation (H₂, CO₂) and use in homogeneous catalysis, with a special emphasis on sustainable catalytic processes. 

Past/current industrial colloborations: Corbion-Purac Corp. (lactide polymerization), SNF Corp. (biodegradable hydrophilic polymers)

Our team welcomes internship applications at the Master level, potential candidates interested in PhD studies as well as post-doctoral candidates.   

Research topics

• Low-coordinated oxophilic metal species (essentially with groups 2, 12 and 13 metal centers), in particular supported by N-heterocyclic carbenes (NHCs),
• Small molecules (H₂, CO₂) activation (H₂, CO₂) with highly electrophilic organometallics based on Al(III), Zn(II) and Mg(II) salts,
• Polymerization catalysis of cyclic esters/carbonates using organometallics for the production of biomaterials,
• Organometallic complexes of Au(I)/Au(III) for use in homogeneous catalysis.
