SSCI-VIDES+EAU+MBE:CDE; International audience; Different methods for the preparation of gold catalysts (mono and bimetallic) were used - the modified deposition-precipitation (MDP), the deposition-precipitation by ammonia (DPA) and the colloidal method (CM). The catalytic performances of all samples were evaluated in the catalytic wet air oxidation (CWAO) of succinic acid under mild conditions (190 degrees C, 50 bar total pressure). The results showed that the preparation procedure and the addition of a second metal (Pt or Ru) clearly influence the catalytic activity and selectivity, depending on the size of the gold particles and the nature of the second metal.
