Molecularly Defined Bio-inspired Hetereogeneous Electrocatalysts
We aim at replicating, in heterogeneous, electrically conductive materials, the active sites of enzymatic system, at least their first coordination sphere. We accordingly investigate site-isolated materials, such as so called “single atom catalysts”, reproducing porphyrin-type active sites, as well as other types of mono or polymetallic assemblies. In addition of enabling a lower distribution of products owing to their narrow site distribution, these catalysts enable for a simpler mechanistic analysis of the catalytic reaction. We couple our studies to in-situ spectroscopic investigations, notably via XAS techniques, leveraging on multiple in-house designed electrocatalytic reactors.
