The reactivity in heterogeneous catalysis and especially in electrocatalysis is very sensitive to the surface structure. To bridge surface reactivity and structure, it is mandatory to work on well-defined surfaces. Single crystal electrodes, for which a single orientation can be put in contact with the electrolyte, represent a very interesting model catalyst for the study of the crystallographic orientation on catalytic activity.
Surfaces can be employed as prepared or modified by deposition of foreign metals to gains new activities. By the way, we are also investigating the mechanism of modification itself, that we are performing using electrochemical deposition. To know more about.
In addition, we use surface X-ray diffraction for in situ characterization of electrodes in operation. To know more about.
