Total Oxidation of Ethanol and Toluene over Ceria-Zirconia Supported Platinum Catalysts.
Original language description
The effect of platinum loading (0.09 - 1.00 wt. %) on the performance of ceria-zirconia supported catalysts in total oxidation of ethanol and toluene in air was investigated. The introduction of platinum promoted the reduction of surface ceria and decreased the acidity of the catalysts. In ethanol oxidation, the temperature of 50 % conversion decreased with increasing platinum content. This increase in catalytic performance was more pronounced for the catalysts with 0.59 and 1.00 wt. % Pt. On the other hand, higher amount of by-products (mainly acetaldehyde) was observed at increased platinum loadings. For all catalysts, a correlation between their H2-TPR profiles and catalytic performance was revealed. In toluene oxidation, only the catalysts with 0.59 and 1.00 wt. % Pt exhibited lower temperature of 50 % conversion than pristine ceriazirconia. The effect of platinum loading was less pronounced than in ethanol oxidation and the correlation between reduction behaviour and catalytic performance was not observed. The superior catalytic performance of the catalysts with 0.59 and 1.00 wt. % of Pt in both ethanol and toluene oxidation was ascribed to the presence of larger platinum nanoparticles, which were not observed at lower Pt loadings.
