Résumé

Amorphous (macro)-mesoporous ZrO₂, TiO₂ and ZrO ₂-TiO₂ have been synthesised and characterised for volatile organic compounds (VOCs) catalytic oxidation. These solids used as catalytic supports present high surface areas. The stability of the porous structure after the calcination at 400°C is observed for ZrO ₂-TiO₂ and TiO₂ but partial breakdown of the structure occurred for ZrO₂ by the crystallisation to tetragonal phase. All these Pd impregnated solids are found to be powerful catalysts for total oxidation of toluene. Pd/TiO₂ presents the highest catalytic potential. The lowest toluene adsorption enthalpy, the low coke content observed after the catalytic test and the highest pore diameter leading to palladium particles more accessible and reducible should explain the interesting catalytic behaviour of Pd/TiO₂.
