Development and characterizations (FT-IR, Solid State NMR spectroscopy, DNP SENS, Elemental analysis, ICP, EFTEM…) of efficient heterogeneous catalysts through the “Catalysis By Design” approach including sol-gel chemistry and surface organometallic chemistry. These topics are of industrial significance since they allows to solve the current energy/environment issues (CH/CC activation/cleavage, CO2 activation…)
