| Abstract: | The Au-Pd/CeO_2 catalysts with different Pd content were prepared by PVP-stabilized reduction method in C_2H_5OH.The catalytic properties of the Au-Pd/CeO_2 catalysts with different Pd content for partial oxidation of methanol were studied.XRD,TPR,H_2-TPD and CH_3OH-TPD were used to characterize the catalysts.The results showed that the addition of Pd could increase the activity and hydrogen selectivity of Au/CeO_2 catalyst for partial oxidation of methanol.When the molar ratio of Au/Pd was 6:4,the activity and hydrogen selectivity of Au-Pd/CeO_2 catalyst was the best. |
