英文摘要 | Mesoporous Pd/ZrO2-TiO2 and PdCu/ZrO2-TiO2 composites with high CO catalytic oxidation performance were successfully synthesized by using mesoporous ZrO2-TiO2 as catalyst support. Both XRD and TEM results indicated that the Pd or Cu species could be homogeneously dispersed in the ZrO2-TiO2 support. The effects of different factors on the CO oxidation property were investigated, including the different kinds of catalyst supports, preparation methods and catalytic promoters. It was found that mesoporous ZrO2-TiO2 as the catalyst support exhibited higher catalytic performance for CO oxidation than mesoporous Al2O3 or SBA-15. In addition, the low-temperature catalytic activity of Pd/ZrO2-TiO2 catalyst prepared by one-step route was greatly enhanced in comparison with traditional impregnation method. More importantly, the co-loaded PdCu/ZrO2-TiO2 catalyst via one-step process showed the optimal catalytic activity for CO oxidation, and the corresponding complete conversion temperature reduced to 170 degrees C which was attributed to the interaction between the Pd and Cu species according to the O-2-TPD analysis. |
