Title
A study of barium doped Pd/Al2O3-Ce0.3Zr0.7O2 catalyst for complete methanol oxidation
Abstract

Al2O3-Ce0.3Zr0.7O2 and 3 wt% BaO doped Al2O3-Ce0.3Zr0.7O2 were prepared by coprecipitation and the supported 0.25 wt% Pd catalysts were compared in the complete oxidation of methanol. The work dealt with a combined investigation of the effect of adding barium on the characteristics of the catalyst and on its catalytic performance of methanol oxidation. The results demonstrate that more active sites at low temperature and more basic sites needed for deep oxidation of methanol are formed after doping barium.
