Description of the research group

The research activities carried out in the laboratory concern electrode mechanisms, interfacial electrochemistry and the property-structure relationship of nano-objects developed at an interface.
The analysis of mechanisms as well as the determination of the kinetic and thermodynamic characteristics of electron transfer (s) allowed us to acquire, for many years, an undeniable expertise in the analysis of complex molecular systems and molecular architectures of nanometric scales.
This research topic is by nature very interdisciplinary. In addition to understanding and replicating the properties of natural systems, this research topic is very closely linked to the development of molecular nanosystems whose functioning involves the intra or extramolecular transfer of electrons.
The efficiency of energy conversion devices or nanoelectronic properties can be greatly enhanced by the use of nanostructured hybrid materials (e.g., organized networks of active nanoparticles or self-assembled materials). One of the goals of our research is to understand and control the electrocatalytic processes at nanostructured interfaces in the perspective of application to energy conversion. Another goal concerns the study of the organization of nanomaterials formed in order to better rationalize the resulting properties.
