| 英文摘要 | the production of hydrogen from oxidative steam reforming of methanol has been tested for ce0.9cu0.(1)ogamma catalysts. the catalysts were prepared by deposition-precipitation (dp), coprecipitation (cp), and complexation-combustion (cc) methods. these catalysts were characterized using bet, tem, x-ray diffraction (xrd), and raman spectroscopy. a solid solution was formed in the ce0.9cu0.(1)ogamma prepared by complexation-combustion. the incorporation of cu atoms into ceo2 lattice leads to an increase of oxygen vacancy. xps results indicated that the cu+ is the main cu species for the ce(0.9)cu(0.1)ogamma-cc sample and the synergistic function between cu2+/cu+ and ce4+/ce3+ occurred in the redox cycle, which is the reason for lower reduction temperatures and improved redox properties as shown in tpr profiles. in the case of the ce(0.9)cu(0.1)ogamma-cp and ce(0.9)cu(0.1)ogamma-dp samples, most cuo dispersed on the ceo2; the poor interaction between cuo and ceo2 does not affect redox properties of ceo2. methanol conversions higher than 85% with 90% hydrogen yield were obtained for ce(0.9)cu(0.1)ogamma-cc from the oxidative steam reforming of methanol at 240degreesc. however, the catalysts prepared by coprecipitation and the deposition-precipitation method showed methanol conversion lower than 30% at 240degreesc, and less than 60% even at 360degreesc. the high catalytic activity of ce(0.1)cu(0.1)ogamma-cc is mainly related to the formation of solid solution and the improved redox properties.
