title: Complete Oxidation of Toluene Over Supported Palladium Catalysts: Effect of Support.
abstract: The catalytic oxidation of toluene was carried out to investigate the effect of the support on the properties and performance of a supported palladium catalyst (1 wt% loading). γ-Al2O3), SiO2 and TiO2 were used as supports. The properties of the prepared catalysts were characterized by XRD, BET, PT, TPD, TPR, XPS and FE-TEM analyses. The experimental results showed that the order of catalytic performance was 1 wt% Pd/TiO2 > 1 wt% Pd/SiO2 > 1 wt% Pd/γ-Al2O3. A strong interaction between the palladium and support was found, which affected the palladium surface concentration and particle size. The higher catalytic activity of the Pd/TiO2 catalyst was attributed to the higher palladium surface concentration and larger particle size.
