Research activities

Reactivity in heterogeneous catalysis, and in particular in electrocatalysis, is highly sensitive to surface structure. In order to link reactivity and surface structure, it is essential to work on surfaces that are well defined at the atomic scale. Single-crystal electrodes, in which a single crystallographic orientation can be brought into contact with the electrolyte, represent a very interesting model catalyst for studying the effect of crystallographic orientation on catalytic activity. The surfaces can be used as they are or modified by depositing other metals to obtain new activities. In addition to conventional electrochemical measurements, we are working on the development of methods for in situ characterisation of electrodes in operation, in particular surface-enhanced X-ray diffraction and tip-enhanced Raman spectroscopy (TERS). (Project TERS_NORMAL ANR-22-CE29-0027).
From a more applied perspective, work is being carried out on the use of iron and nickel-based alloys for oxygen release for water electrolysis in an alkaline environment  (Projet PEPR-H2 DAEMONHYC).
