Université de Poitiers - Institut de Chimie des Milieux et Matériaux de Poitiers (UP-IC2MP)

UP-IC2MP is a Joint Research Unit between the University of Poitiers and the CNRS (Centre National de la Recherche Scientifique). It is organized in six teams working in the fields of environment, fine chemistry and energy, namely: (i) Catalysis by metals; (ii) Catalysis by oxides; (iii) Electrocatalysis, (iv) Catalysis by Sulphurs, (v) Zeolites, and (vi) Theoretical chemistry. Most of the activities devoted to catalysis focus on the controlled preparation and characterization of catalytic materials as well as in understanding reaction mechanisms. Mono- or plurimetal catalysts are synthesized by various methods of "la chimie douce", i.e., surface redox processes, surface reactions via organometallic complexes, local modifications, grafting of catalytic precursors over modified surfaces, and preparation of mixed compounds. In addition to dispersing the active phase, the support plays a major role in some steps of the reaction mechanism (surface acido-basic properties, transfer of the reaction intermediates between the metal and the support).

 

The concepts of the interfacial electrochemistry with those of the heterogeneous catalysis pave the way to the elucidation of the reaction mechanisms in order to manufacture more active and selective electrode materials in the nanoscale domain as mono- and bi-metal compounds of well-controlled composition. To reach this purpose, analytical and spectroscopic techniques, coupled to electrochemical methods, are combined, such as infrared reflection spectroscopy (FTIR), in line mass spectrometry (DEMS), X-ray absorption (EXAFS). Other physico-chemical techniques for the characterization of model nanostructured electrocatalysts are available at UP-IC2MP (e.g. electronic microscopy, X-ray diffraction, chemical analysis, Raman, DTA-TGA).

 

The electrocatalysis team is actively involved in national and international cooperation through a variety of actions, including joint research programs funded e.g., by the French national agency (ANR), contracts (University of California), exchange of research fellows.
