 Preparation of supported mono- and bi-métallic catalysts by deposition-reduction or reduction-deposition: control of the different steps of catalyst preparation, in order to form highly dispersed metal nanoparticles of controlled size

  • Metal-oxide support interaction: Influence of the properties of oxide supports on catalytic properties of supported metal
  • Application to gold catalysts: Synthesis, Characterization and Catalytic reactivity
  • Development of gold-based bimetallic catalysts for reactions of oxidation and selective hydrogenation
  • In situ and operando characterisation of bimetallic nanoparticles under activation and reaction conditions; study of possible particles restructuring.
