The Complete Oxidation of Ethanol at Low Temperature over a Novel Pd–Ce/γ-Al2O3–TiO2 Catalyst

Pd–Ce/γ-Al2O3–TiO2 catalysts were prepared by combined sol–gel and impregnation methods. Transmission electron microscopy, X-ray diffraction, H2-temperature-programmed reduction, O2-temperature-programmed desorption, and ethanol oxidation experiments were conducted to determine the properties of the catalysts. Addition of an optimal amount of Ce improved the performance of the Pd/γ-Al2O3–TiO2 catalyst in promoting the complete oxidation of ethanol. The catalyst with 1% Ce exhibited the highest activity, and catalyzed complete oxidation of ethanol at 175 °C; its selectivity to CO2 reached 87%. Characterization results show that addition of appropriate amount of Ce could enrich the PdO species, and weaken the Pd–O bonds, thus enhancing oxidation ability of the catalyst. Meanwhile, the introduction of CeO2 could make PdO better dispersed on γ-Al2O3–TiO2, which is beneficial for the improvement of the catalytic oxidation activity.
