Our research targets the synthesis of novel organometallic species, through ligand design, that will tackle the most challenging reactions of our century. On one hand, novel species that involve metal - carbocation Z interaction, and late – late transition metal bimetallic will be synthesized, studied at the fundamental level and used as homogeneous catalyst for CO2 conversion, N2 and CH activations. On the other hand, new methodology in anode synthesis will be developped in order to obtain highly effective and well-defined electrodes for energy production using Direct Alcohol Fuel Cells.Show Less
