| 英文摘要 | monolithic catalysts were prepared by washcoating ce0.8zr0.2o2 slurries and then impregnating platinum or rhenium onto cordierite substrates, and characterized by brunauer-emmett-teller (bet), x-ray diffraction (xrd), inductively coupled plasma (icp), temperature-programmed-reduction (tpr) and temperature-programmed deposition of co (co-tpd) techniques. the effects of preparation parameters on the catalytic performance for water gas shift (wgs) reaction were investigated in details, including different ce0.8zr0.2o2 powder as washcoat, coat loadings, metal loadings, pt/re weight ratio and impregnation sequences. in addition, pyrophoricity (exposure to oxygen stream) and long-term stability were carried out over monolithic catalysts with the optimized composition. the results showed that ce0.8zr0.2o2 prepared by microemulsion methods was the preferred washcoat, and that 50wt% ce0.8zr0.2o2 coat loading and 0.68wt% pt loading were required to reduce co content to ca. 1%. the optimal catalytic performance was achieved over 0.11 wt% re/0.34wt% pt/50wt% ce0.8zr0.2o2-m/cordierite catalyst. pyrophoricity tests indicated that no obvious activity loss was observed over 0.11 wt% re/0.34 wt% pt/50wt% ce0.8zr0.2o2-m/cordierite catalyst after three exposures to oxygen; while 17% of the initial activity was lost over industrial b206 after one exposure. monolithic 0.11wt% re/0.34wt% pt/50wt% ce0.8zr0.2o2-m/cordierite catalyst exhibited good stability during 80h on-stream test.
