    Abstract
  • The catalytic performance of Pd/Al2O3-TiO2, V/Al2O3-TiO2 and V-Pd/Al2O3-TiO2 with different vanadium contents prepared by impregnation method for the complete oxidation of ethanol and acetaldehyde has been investigated. The result indicated that the appropriate amount of vanadium oxide (1%~3%) can modify the characters of Pd/Al2O3-TiO2 catalyst distinctly, and improve the catalytic activity of complete oxidation of ethanol and acetaldehyde. The relationship between surface characters of catalyst and the activity was studied by means of XRD, NH3-TPD, N2 adsorption. The results indicated that Pd/Al2O3-TiO2 catalyst added with proper vanadium content which showed the best catalytic performance result in the proper superficial acidity, the proper surface area and pores of the catalyst, and that has revealed a strong interactions among V, Pd and the carrier.
